The wise does at once what the fool does at last.

If you think you can do it, you can.

Things do not happen. Things are made to happen.

Quality is not an act, it is a habit.

The secret of getting ahead is getting started.

Know or listen to those who know.

I can, therefore I am.

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

Be gentle to all and stern with yourself.
