The world doesn't care about your self-esteem.The world will expect you to accomplish something feel you feel good about yourself.
If you think your teacher is tough, wait till you get a boss.
Flipping burgers is not beneath your dignity.Your Grandparents had a different word for burger flipping...opportunity.
If you mess up, it's not your parents' fault, so don't whine about your mistakes, learn from them.
