To know oneself, one should assert oneself.

Never complain and never explain.

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

If you think you can do it, you can.

If you're going through hell, keep going.

Things do not happen. Things are made to happen.

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

Leap, and the net will appear.

Expect problems and eat them for breakfast.
