It's always too early to quit.

What you do today can improve all your tomorrows.

Know or listen to those who know.

Always desire to learn something useful.

Do not weep do not wax indignant. Understand.

Be thine own palace, or the world's thy jail.

If you think you can do it, you can.

Expect problems and eat them for breakfast.

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