It's always too early to quit.
If you can dream it, you can do it.
After a storm comes a calm.
To be a good loser is to learn how to win.
To know oneself, one should assert oneself.
The wise does at once what the fool does at last.
Wherever you are - be all there.
Well done is better than well said.
If you think you can do it, you can.
What you do today can improve all your tomorrows.
People who keep stiff upper lips find that it's damn hard to smile.
