To know oneself, one should assert oneself.

By failing to prepare, you are preparing to fail.

Know or listen to those who know.

Wherever you are - be all there.

Well done is better than well said.

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

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

What you do today can improve all your tomorrows.

Never complain and never explain.
