To know oneself, one should assert oneself.

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

Do not weep do not wax indignant. Understand.

Be thine own palace, or the world's thy jail.

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

If you think you can do it, you can.

Well done is better than well said.

Never complain and never explain.

Quality is not an act, it is a habit.
