You never know what motivates you.

Always desire to learn something useful.

Do not weep do not wax indignant. Understand.

Know or listen to those who know.

It's always too early to quit.

Either you run the day or the day runs you.

Things do not happen. Things are made to happen.

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

If you're going through hell, keep going.
