Not everybody will like what you do even it is a good thing. So, be prepared! There will be somebody that will try to knocked you down and their eyes are burned when they see you successful. They will do whatever it takes to see you fall down, failed and stop doing your thing!
Actually, they were wrong. They thought that when they do all kind of bad stuff and be mean to you they will make you give up! It's not like that. The more they try to stop you, the more stronger you will be. You will try to discover much more talent or creativity or whatever it is that you need in you! Yeah...believe me. They maybe successful to make you cry, sad and upset but all those feelings never last. When the time come, you will rise like the phoenix from the ashes and fly high to the sky!!! Yeah!!!
So, what to do...never give up...organize your feelings so that you not miserable all the time to all the people around you...yeah you can!!!
p/s: believe me you can even you thing u can't! (Do I sound positive enough? haha)
