It's always too early to quit.

Things do not happen. Things are made to happen.

Be gentle to all and stern with yourself.

You never know what motivates you.

Do not weep do not wax indignant. Understand.

If you've got a talent, protect it.

Expect problems and eat them for breakfast.

Quality is not an act, it is a habit.

The most effective way to do it, is to do it.
