It's always too early to quit.
After a storm comes a calm.
If you can dream it, you can do it.
What you do today can improve all your tomorrows.
Who seeks shall find.
Without hard work, nothing grows but weeds.
If you think you can do it, you can.
Quality is not an act, it is a habit.
To be a good loser is to learn how to win.
Know or listen to those who know.
Failure happens all the time. It happens every day in practice. What makes you better is how you react to it.
