Be gentle to all and stern with yourself.

To know oneself, one should assert oneself.

Wherever you are - be all there.

The most effective way to do it, is to do it.

The secret of getting ahead is getting started.

If you think you can do it, you can.

If you can dream it, you can do it.

The dog that trots about finds a bone.

Quality is not an act, it is a habit.
