If you think you can do it, you can.

What you do today can improve all your tomorrows.

Always desire to learn something useful.

Be gentle to all and stern with yourself.

Know or listen to those who know.

Without hard work, nothing grows but weeds.

If you're going through hell, keep going.

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

To know oneself, one should assert oneself.
