It's always too early to quit.
Never complain and never explain.
The wise does at once what the fool does at last.
After a storm comes a calm.
You never know what motivates you.
Always desire to learn something useful.
Without hard work, nothing grows but weeds.
To be a good loser is to learn how to win.
If you've got a talent, protect it.
Problems are not stop signs, they are guidelines.
I've studied all my musical life, but learning is only good if you do something constructive with it.
