It's always too early to quit.

By failing to prepare, you are preparing to fail.

Know or listen to those who know.

If you're going through hell, keep going.

Quality is not an act, it is a habit.

What you do today can improve all your tomorrows.

Be gentle to all and stern with yourself.

To know oneself, one should assert oneself.

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