Do more, provide more, go further than you are paid for. Don't just give more stuff, give more stuff that people really want and appreciate. Affect others profoundly. Get out of the roles and job descriptions we all have. Whatever it takes, make an impact on your world.
Time is expensive, and wasting it is unattractive and irritating.
Thrive on the details. Pay attention to the subtleties, the small things. It's the little extras that build you up, and the little slips that bring you down. Orient life around your values. And, in addition, you will gain the courage and conviction that your hunger, cravings, and weight problems are not your fault, and as the pounds fade, so will your guilt and self-blame.
