It's always too early to quit.

Do not weep do not wax indignant. Understand.

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

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

Never complain and never explain.

If you're going through hell, keep going.

The secret of getting ahead is getting started.

You never know what motivates you.

Quality is not an act, it is a habit.
