Don't be serious, enjoy life as it comes.

Enjoy life. This is not a dress rehearsal.

He that would enjoy life and act with freedom must have the work of the day continually before his eyes. Not yesterday's work, lest he fall into despair, nor tomorrow's, lest he become a visionary, nor that which ends with the day, which is a worldly work, nor yet that only which remains to eternity, for by it he cannot shape his actions.

Even if you have a terminal disease, you don't have to sit down and mope. Enjoy life and challenge the illness that you have.

Your purpose in life is to find your purpose and give your whole heart and soul to it

Without health life is not life; it is only a state of langour and suffering - an image of death.
