Appreciate those who don't believe

I was talking to my brother last night and he was telling me how many people do not believe in him. I told him to appreciate that. When people don't believe in you that gives you a infinite amount of motivation. When you lose focus, lose confidence, lose your will to go forward, just think about how many people would be right about you if you were to quit. These people are hoping for your downfall. Don't you dare give them the satisfaction of being right about you. Use their negative energy as a new source of motivation. When you achieve your goals, these same people who didn't believe in you will be drawn to you, and that is because without even knowing it, they helped you succeed.
