Learning about great people and their work is good. But this does not change us.
What changes us is "Exercises" that we do. It is the exercises which shape our brain and body.
If we do brain exercises, brain sharpens, if we do physical exercises, our body develops.
Here, Law of Cause and Effect works with some assurance.
Whether we want or not, our Exercises changes our mind and body.
