It's always too early to quit.
After a storm comes a calm.
Problems are not stop signs, they are guidelines.
Quality is not an act, it is a habit.
If you can dream it, you can do it.
Well done is better than well said.
The wise does at once what the fool does at last.
If you think you can do it, you can.
To be a good loser is to learn how to win.
Leap, and the net will appear.
Don't clap too hard - it's a very old building.
There's no such thing as failure - just waiting for success.
