Left-handedness has long posed a challenge in many cultures, as nearly everything has been designed for right-handed individuals. I also have a relative who is left-handed, and the school saw no issues in that regard. He was an excellent student, graduated with top grades, and went on to a professional school where he had to use specialized instruments. The issue? Most of the instruments were, once again, designed for right-handed users.

He struggled significantly to find left-handed instruments, and he wasn’t alone. I also had a friend who was left-handed and enjoyed playing golf. Most golf equipment is similarly designed for right-handed players. Again, he faced difficulty finding left-handed golf clubs. But one time, he had a great chuckle when someone stole his golf clubs from the trunk of his car. “I wonder how surprised they’re going to be when they find out they can’t use those clubs because they’re made for a left-handed golfer,” He said with a glorious smile on his face.

Have you ever tried using your opposite hand to perform your daily activities? Do you believe that training your non-dominant hand can open up new creative channels or stimulate old, dormant brain regions? Recent studies show that the benefits of non-dominant hand training might be more useful than previously thought, yet more complex.

Have you ever thought about what would happen if you started using your “other” hand for everyday activities? Perhaps you have heard claims that training your non-dominant hand can unlock hidden creativity or tap into unused parts of your brain. The reality is more complex than these claims, but recent research has provided some interesting insights into what happens when we try to use our non-dominant hand.

What the Science Shows

The idea that using your non-dominant hand will suddenly make you more creative is largely a myth. As researchers have found, while blogs and self-help articles often promise dramatic cognitive boosts, the scientific evidence tells a different story. Any improvements you gain will likely be specific to the skills you practice, rather than providing a general creativity enhancement.

Actual Changes in Your Brain

When you persistently train your non-dominant hand, measurable changes occur in your brain. Studies using advanced brain imaging have shown that sustained practice with your non-dominant hand creates new neural pathways and strengthens existing ones. This process, called neuroplasticity, demonstrates your brain’s remarkable ability to adapt and reorganize itself.

For example, research on precision drawing with the non-dominant hand revealed increased functional connectivity among various brain regions involved in hand control and movement planning. Similarly, studies on learning to use chopsticks (granted, most of us rarely use chopsticks) with the non-dominant hand showed significant changes in brain activity patterns after just a few weeks of practice.

A Possible Schedule to Use

The following is based on research in this area, but it serves as a simple and potential guide for anyone who wants to test some of the research theories. This is not a specific training program for anyone, but a more recreational activity. Remember that research always has imperfections, and some of these results are due to the samples used, the areas where it was conducted, and the researcher’s own biases.

Training your non-dominant hand requires a structured approach, which begins with fundamental skills before advancing. If you think you will be turned into a Picasso or a best-selling author because of these exercises, you may be disappointed. There was only one Picasso, but you can possibly improve some things for yourself. Exactly what they will be, at this point, is an unknown. Daily practice of 15–20 minutes may lead to enhanced abilities.

Start with the basics (Weeks 1–2)
Write your name slowly with your non-dominant hand, followed by practicing the alphabet and basic words. The initial appearance of your writing does not need to be perfect. Back to that time in elementary school when you were first learning your alphabet, and how your handwriting had to be improved by repeatedly drawing circles and then letters. Using the non-dominant hand will be very much like the initial learning. This is the handwriting part of your exercise.

Now, draw basic shapes, including circles and lines, while concentrating on maintaining control rather than achieving perfection. The initial exercises help your brain learn fundamental motor patterns, which serve as a foundation.

Move into daily life (Weeks 3–4)
After gaining control of your writing movements, begin using your non-dominant hand for basic everyday activities. Begin by using your non-dominant hand to hold your coffee cup and use a spoon to eat during meals, starting with basic foods.

Do not attempt this while using hot liquids or foods in your non-dominant hand. We don’t want anyone to have an unpleasant experience. So, care is the watchword here. Spend daily intervals with your computer mouse positioned on the opposite side of your normal use. This technique helps you connect your practice sessions to actual, real-world applications.

Refine your skills (Weeks 5–8)
Progress to performing more accurate tasks with your non-dominant hand. The activities you should attempt next include threading needles, using scissors for basic cuts, and brushing your teeth. Add creative elements too — spend time drawing, painting, or playing instruments if you have them.

Master advanced coordination (Week 9+)
The last step involves performing complex tasks that will push your abilities to their limits. The brain development process benefits significantly from learning to use chopsticks, while activities like playing catch and writing whole paragraphs integrate all your learned skills. Progressively incorporate your non-dominant hand into your hobbies, cooking activities, and problem-solving tasks. But always proceed cautiously with every activity in which you will engage.

Will this program work for you? Only you can make that determination, and you are also the one who will decide whether you want to engage in this activity. It might be interesting, it might be useful, or it might be something you decide to toss aside. No harm.

Progress is impossible without change, and those who cannot change their minds cannot change anything. George Bernard Shaw.

I first learned about kaizen as a young doctor at a pioneering Seattle hospital. Virginia Mason Medical Center introduced the Toyota Production System to health care.

More recently, I have tried to apply kaizen to my life. Here’s my bottom line: I try to get one percent better daily. Yes, I know I will not achieve that amount most days.

I can be a better me by making small, incremental improvements over months, years, and decades.

What is Kaizen?

Kaizen is a business philosophy focusing on continuous improvement across an organization.

This approach helps companies focus on consistently increasing efficiency. The process helps to eliminate waste.

Kaizen encourages input from any employee. One can be a factory worker or a C-suite member and contribute.

Americans Created Kaizen

Did you know that the kaizen system was developed in the United States? Americans developed this small-step work improvement approach under the Training Within Industry program (TWI Job Methods).

As part of the Marshall Plan after World War II, American occupation forces brought experts to help rebuild Japanese industry.

At the same time, the Civil Communications Section (CCS) developed a management training program that taught statistical control methods as part of the overall material.

Kaizen in Japan

The kaizen method became popular in post-war Japan with manufacturers like Toyota.

In the Toyota Production System, for instance, if a line worker sees an issue, they stop production and create a solution with their supervisor.

Did you notice that those involved in the daily work have the authority to make changes without formal approval from upper management?

There is no long and drawn-out process to create change. The process facilitates continuous improvement.

Deconstructing Kaizen

改 + 善

You know that kaizen means continuous improvement in Japanese. Unfortunately, the word’s meaning is frequently lost when translated into English.

Let‘s deconstruct kaizen. The first kanji 改 (Kai) refers to change. The second one, 善 (Zen), means good or change for the better.

We can further deconstruct the first character, Kai, into two parts. The left portion refers to the self. The right part is a picture of a person’s back after being whipped.

Putting it all together, we see 改 can be reduced to “self” and “whip.” Put them together, and my mind goes to “whip oneself into shape.” Moreover, the character is used for the word revolution, suggesting big change.

Let’s move to the second kanji, “Zen.” Reading from top to bottom, we see 羊 (“hitsuji” or sheep). The bottom portion refers to an altar, translating to sacrificing a lamb on an altar.

Combining “Kai” and “Zen” thus leads to this: Each individual makes sacrifices for the entire group’s improvement.

Kaizen As A Mindset

Physicians and other staff members from my former hospital regularly visited the Toyota plant outside Nagoya (Japan) to study the Toyota Production System (TPS).

Even if you have yet to participate in lean project management in manufacturing (or other industries), you may be catching on to the approach’s effectiveness.

The message of the Kaizen strategy is that not a day should go by without some improvement being made somewhere in the company. — Masaaki Imai.

Kaizen Craftsmanship: Sculpting Your Success One Step at a Time

I love making small, incremental changes to improve my life and achieve my goals.

When I travel to Japan, I see elements of kaizen everywhere. The Japanese believe that even tiny changes, when applied consistently, can compound to create excellence.

I certainly have grand goals — I want to compete in a Master’s bodybuilding competition in 2024 — but sometimes it is less stressful to take the kaizen approach.

Self-Improvement As A Process (not a Goal)

So many view self-improvement as a destination. Reach your goal, and voila! You are done.

But what if you could aim to get one percent better daily? Small, incremental improvements — kaizen — over months, years, and decades can lead to extraordinary outcomes.

You know what to do; now, make small, continuous improvements in your process.

Here are some of the ways I use kaizen in my daily life:

• Exercise. While I exercise a lot now, I started doing two sets of ten push-ups. In three months, I did 100 (ten sets of ten) push-ups in the morning.
• Morning and evening routines. I started with the evening, focusing on the ten minutes before bed. I created habits, including brushing my teeth for ten minutes, flossing, and using a non-alcoholic rinse. I also aimed to read for 30 minutes, dodging blue light-emitting electronics. Then I turned to the morning.
• Mindfulness. I struggle with this one. Vinyasa flow yoga was not a fit for me. So what did I do? I began with one minute of breathing exercises. I increased over time and now do ten to 15 minutes of mindfulness meditation.
• Diet. This one is a work in progress. I began by cutting out one sugary drink daily, putting aside my morning ritual of a glass of orange juice.

Final Thoughts

I begin each journey with one small goal, incrementally and slowly improving over time. As is the case with effective investment, time is my ally.

Self-improvement as a process rather than a destination.

“The Kaizen Philosophy assumes that our way of life — be it our working life, our social life, or our home life — deserves to be constantly improved.” — Masaaki Imai.
