It's always too early to quit.

Begin to be now what you will be hereafter.

If you think you can do it, you can.

Be gentle to all and stern with yourself.

The dog that trots about finds a bone.

If you're going through hell, keep going.

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

The secret of getting ahead is getting started.

Quality is not an act, it is a habit.
