New here!

Hi! I am new to MFP and thought I would give it a try. I don't have the best track record of finishing programs that I have started. I have tried WW about 5 times, and started the C25K last summer, but only got through week 5. I am hoping this time will be different as I would like to lose about 20 lbs. minimum. The silliest part is I would really like to wear shorts this summer without feeling super self-concious!
