Don't ever let anyone break your soul. You have to stand on your own two feet and fight. There are those who would give anything to see you fall. Never give them the satisfaction. Hold your head up high. Put a smile on your face and stand your ground.
Sometimes I really need to remember this. Just because no one's giving you any credit and they aren't treating you very well, doesn't mean you should stop doing your best and working hard to do better.
