Always take the good and the bad. Own up to your mistakes. If you make a mistake, you prove you are doing something worthwhile. If you make no mistakes, you must not be doing anything. Make sure every mistake you make causes you discomfort.
People tend to protect themselves from pain.
Don't let anyone be scared of you. Open communication is the greatest communication. If you hate your work, quit. Luck is not how you get success. Hard work is not how you get success.
