Experience.

Nothing beats it...I had a friend that was going through stuff and I was like...you know when you get chicken pox really bad you never get it again. Just like when you get burned by relationships/jobs/money/friends..it doesn't hurt has bad if you really go through a bad one. Thicker Skin is so important to just achieve a greater happiness and peace. You also have to understand that you control so little in this world. It is all one big cluster.....I am just glad I am in America. This place rocks.
