It's always too early to quit.
Either you run the day or the day runs you.
Problems are not stop signs, they are guidelines.
Do not weep do not wax indignant. Understand.
The wise does at once what the fool does at last.
By failing to prepare, you are preparing to fail.
If you've got a talent, protect it.
Quality is not an act, it is a habit.
If you think you can do it, you can.
Leap, and the net will appear.
You can no more win a war than you can win an earthquake.
