i am thankful for all those difficult people in my life. they have shown me exactly who i do not want to be. Hypocrites and the like who act one way at school and behave totally different in their homes. People who believe in one thing but act another.
Don't bother with hypocrites or judgmental people who criticize you and put you down. They are too shallow to recognize their own weaknesses. It's easier for them to try to make others feel bad than to look in the mirror at their own pathetic behaviors.
