Leap, and the net will appear.

If you think you can do it, you can.

Be gentle to all and stern with yourself.

Know or listen to those who know.

Quality is not an act, it is a habit.

To know oneself, one should assert oneself.

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

Well done is better than well said.

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