As a kid I practiced Judo which is a martial art as well as a philosophy. And my Judo teacher gave us a philosophical story which I came to understand only recently and which helped me achieve more than I though was possible. So I wanted to share it.

Recently I got the urge to write again so I gave this blog a new coat of paint, and decided to give a brief history, the reason I stopped writing and an explanation as to why I moved away from Medium.
