I am a strong fan, if not fanatic , of the world of Personal Development. One of resources is of course Youtube. Are they reliable? Before I follow that perticular youtube, I will review as many as I could their posts. Currently I have so many of personal development Youtube I like. Can check my FB too on this. A lot of link there. My top one is Tai Lopez. Some people say he is a Scam. That not important. This guy is superb. A lot of insights you can learn from him. He is full of wisdom because he reads one book a day. Sometimes he is sharing some ideas on how his friends making million dollar a day! Is not that great?! That why people say he is a scam... I do not think so. Most important he has a lot of great insight. He is very positive. We need to hang out with this kind of people. They open up my mind for new possibilities.
