Know or listen to those who know.

You never know what motivates you.

It's always too early to quit.

Be kind whenever possible. It is always possible.

Do not weep do not wax indignant. Understand.

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

Things do not happen. Things are made to happen.

If you've got a talent, protect it.

Quality is not an act, it is a habit.
