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

Problems are not stop signs, they are guidelines.

Be gentle to all and stern with yourself.

Quality is not an act, it is a habit.

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

If you're going through hell, keep going.

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

It's always too early to quit.

The secret of getting ahead is getting started.
