Never complain and never explain.

Be gentle to all and stern with yourself.

It's always too early to quit.

Only the educated are free.

Do not weep do not wax indignant. Understand.

If you're going through hell, keep going.

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

Quality is not an act, it is a habit.

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