Where to find motivation!!

I would think that living longer, not getting diabetes and other benefits of losing weight would be enough. I have no idea what motivates me. I have lost weight and been close to my target twice in my life. The only common ground was that I loved my job ... hmmm

But I have two motivational events in my future. I am working to lose 10 to 20 pounds to ...
1. Look good on the Cruise and party with my family on March 13. Being about 9 weeks away is perfect... not too long, not too short.
2. The Durham Great Human Race is scheduled for March 29th, just 2 weeks after the party. I really really really want to lose 10 to 20 pounds in order to improve my time from last year. I think I can shave 3 to 7 minutes off if I lose weight by running and improve my running by losing weight.
