This is part of the importance of knowing thyself, the path to wisdom. Wisdom is about right-action, and that is to know the difference between what is right and wrong, i.e. morality. I have explained this before in other posts. Self-knowledge eventually leads to morality as the path to greater wisdom for living. Philosophy is the love of wisdom. Learning how to think is part of that. We need to think deeper and better so that we can realize what is going on and why it's happening.

I had the thought that your post as much as they benefit others are still helping you on your own journey. Then I started reading that LOL :D

I think the question of How to change the world? is answered quite well here , you did a great job of outlining and explaining the importance of self change to effect real change.
