To know oneself, one should assert oneself.

By failing to prepare, you are preparing to fail.

Know or listen to those who know.

If you're going through hell, keep going.

Things do not happen. Things are made to happen.

If you've got a talent, protect it.

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

Never complain and never explain.

Quality is not an act, it is a habit.
