I can, therefore I am.

Quality is not an act, it is a habit.

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

Always desire to learn something useful.

If you're going through hell, keep going.

To know oneself, one should assert oneself.

Leap, and the net will appear.

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

If you've got a talent, protect it.
