If you are gonna live your life, just try to not be crazy, have fun but have some focus and some purpose and try to know what that is. If you don't know now, try to figure it out.
I don't pay attention. I don't read stuff or message boards because you definitely get affected. You can read a hundred great comments, amazing comments, and have one bad one and that is all you can focus on and it wrecks your day. It says something about negativity and how it draws us somehow.
