You must find something you want to live for that's bigger than yourself - a mission - whether it's your children, a business, a non-profit, whatever. That pulls you to achieve, which is far more sustainable than to push yourself to. You can only push yourself for so long.
Tony RobbinsWe can all reduce our life to a description that makes people feel sorry for ourselves or we can expand our life to a dimension where we connect and give to others.
