Be gentle to all and stern with yourself.

Wherever you are - be all there.

Know or listen to those who know.

The dog that trots about finds a bone.

Go for it now. The future is promised to no one.

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

If you're going through hell, keep going.

Always desire to learn something useful.

What you do today can improve all your tomorrows.
