Without hard work, nothing grows but weeds.

Be gentle to all and stern with yourself.

If you think you can do it, you can.

Quality is not an act, it is a habit.

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

If you're going through hell, keep going.

I can, therefore I am.

Leap, and the net will appear.

To know oneself, one should assert oneself.
