Never complain and never explain.

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

Be gentle to all and stern with yourself.

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

It's always too early to quit.

Quality is not an act, it is a habit.

The dog that trots about finds a bone.

What you do today can improve all your tomorrows.

The secret of getting ahead is getting started.
