If you think you can do it, you can.

Things do not happen. Things are made to happen.

The secret of getting ahead is getting started.

The dog that trots about finds a bone.

If you're going through hell, keep going.

To know oneself, one should assert oneself.

Quality is not an act, it is a habit.

By failing to prepare, you are preparing to fail.

Be gentle to all and stern with yourself.
