I’ve watch this before but like a good book, video/lectures affect you depending on what “you” is while you are watching it.
I don’t know why I asking myself this question repeatedly , but I’ve made it a weekly weekend thing to ask myself.
-Are your really happy?
-What’s keeping you from being happy?
-What would/could you change to be happy?
and the answers maybe a bit zen but as my previous post said. failure and success is the same thing.
