We will become what we thought, everything around us are only beliefs. Do what you truly want to do and see the universe like God sees it. And do not forget, this vast place called is no more than an atom on tip of a needle compared to vastness of the universe, and anything we do -regardless of how much they are good or bad- can do significant harm to it so get easy on yourself.
You can write anything about me into this page, even if I get angry or sad, my sadness or anger can not harm you, can they?
