to SP! This really is a great site - lots of resources and so many great people ready to encourage you.
I see you've designed your Spark Page You might want to think about making it public, so people can visit you and support you. Another good way to meet people and make friends is to join a few teams and post on the message boards of your teams. I have found that my Spark friends are my greatest motivation.
Another suggestion - don't try to do too much all at once... that can set you for failure. It's best to start out with one or two things you can really commit to - like tracking your food, and exercising at least 15 minutes a day. Then as you feel ready, you can add on more.
