Why get bitter towards those who don't believe in your dreams, when they don't even believe in theirs?
~ Hafiz
Don't get bitter and discouraged because most people don't believe in you; instead, get better with believing in yourself in doubtful times.
Try not to get bitter because a lot of people don't believe in you; instead, be proud that you still believe in yourself despite the fact they don't see what you see in yourself.
