Life is not fair. Get used to it! Stop expecting life to hand you things you think you deserve.
The world doesn't care about your self-esteem. Start making something of yourself today. Right Now.
You will not make a six-figure salary after school. You will have to work hard for what you get.
Flipping Burgers is not beneath your dignity. Swallow your pride and take that job you think is beneath you as a stepping stone.
If you mess up, it's not your parent's fault. Stop spreading the blame around and take responsibility for your failures.
Your parents know something you don't. Perhaps, before you were born, your parents weren't as boring as they are now.
Your school may have done away with winners and losers but life has not. The result of an exam does not justify the means. It doesn't bear the slightest resemblance to anything in real life.
Life is not divided into semesters. Once life starts, it just goes on and on. So spend your time doing something worthwhile.
What you see on TV is not real life. In real life, people actually have to leave the coffee shop and go to jobs.
