I can, therefore I am.

Quality is not an act, it is a habit.

You never know what motivates you.

If you think you can do it, you can.

If you've got a talent, protect it.

Leap, and the net will appear.

The wise does at once what the fool does at last.

It's always too early to quit.

Do not weep do not wax indignant. Understand.
