Quality is not an act, it is a habit.

If you think you can do it, you can.

Know or listen to those who know.

You never know what motivates you.

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

Be gentle to all and stern with yourself.

Expect problems and eat them for breakfast.

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

To know oneself, one should assert oneself.
