In my organization, we use the concept of kaizen, a Japanese word describing continuous improvement.
In one of its simplest forms, kaizen calls for the practitioner to do something for one minute every day at the same time. By breaking down a task to something that can be done in one minute, we eliminate all excuses not to tackle that task. By doing it at the same time, we create a habit. By doing it every day, we accomplish great things over weeks, months, and years.
This idea can be applied to creating a painting, reading a book, writing a book, learning a language, getting better at a videogame, and getting in shape.
Of course, it can also be applied to becoming an ethical leader.
