Be kind whenever possible. It is always possible.

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

The dog that trots about finds a bone.

Quality is not an act, it is a habit.

By failing to prepare, you are preparing to fail.

It's always too early to quit.

Be gentle to all and stern with yourself.

To know oneself, one should assert oneself.

Either you run the day or the day runs you.
