Learn from your mistakes. We all make misteaks (oops). When you learn from your mistake, hopefully you will avoid making the same mistake again. If your mistake involves another person and you hurt them, apologize for the mistake. Mistakes are part of life. That's why there is "Delete" on the computer. Even when people try their best, they still make mistakes. If you can correct your mistake, try to correct it. Learn from mistakes and move on.
