Wow, what a great post! I think everyone tries to analyze their life, actions, G-d given talents and the effect they have and could have on others and the world. Some see it with more clarity and are therefore able to adapt and modify as they go along.
Some of the best people I know, privately “move mountains”, and dont look for notoriety. They dont need it, they dont want it. If we would try to emulate those, the world would be a better place.
