Be kind whenever possible. It is always possible.

It's always too early to quit.

What you do today can improve all your tomorrows.

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

If you're going through hell, keep going.

Know or listen to those who know.

Either you run the day or the day runs you.

Expect problems and eat them for breakfast.

By failing to prepare, you are preparing to fail.
