If you do not enjoy what you are doing, you will never be good at it.
Worst feeling in the world is knowing you did the best you could, and it still wasn't good enough.
Yesterday no longer matters. What matters the most is tomorrow.
If people are trying to bring you down, it just means you're above them.
"A smile doesn't always mean a person is happy. Sometimes it simply means they are strong enough to face their own problems."
All you need to change is will.
