It's always too early to quit.
Well done is better than well said.
Quality is not an act, it is a habit.
After a storm comes a calm.
What you do today can improve all your tomorrows.
You never know what motivates you.
Things do not happen. Things are made to happen.
The wise does at once what the fool does at last.
Go for it now. The future is promised to no one.
To be a good loser is to learn how to win.
I used to spend every morning in detention at my old school.
