If you think you can do it, you can.

You never know what motivates you.

Things do not happen. Things are made to happen.

If you're going through hell, keep going.

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

The secret of getting ahead is getting started.

The dog that trots about finds a bone.

Quality is not an act, it is a habit.

To know oneself, one should assert oneself.
