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.

If there's anything you're not happy about-in your relationships, in your health, in your career-make a decision right now about how you're going to change it immediately.

Everything happens for a reason and a purpose, and it serves you.

If you want anything to change, you've got to change it. If you want things to get better, you've got to get better. And the only way to really do well in life is to find more value than anybody.

Stay committed to your decisions, but stay flexible in your approach.

I naturally end up looking for things to be grateful for. It doesn't mean I don't sometimes feel angry or fearful but because I'm wired for positive emotions, net, I end up treating others and myself better.

You must learn how to handle rejection. To succeed, you must learn how to cope with a little word 'no', learn how to strip that rejection of all its power. The best salesmen are those who are rejected most. They are the ones who can take any 'no' and use it as a prod to go onto the next 'yes'.
