STOP PAYING ATTENTION TO NEGATIVE PEOPLE PULLING YOU DOWN.
Never give attention to those laughing at you. By the way, you likely may not have heard over 85% of what has been negatively said about you.
When you are getting better, they will say you are proud.
When things are tough, they will say, you are a failure.
Don't compete..don't try to prove any point. It is of no use trying to fight with your past....
