Let's try this again

Well, I'm a 32 year old father of two with hectic work as a physician. My whole life I've seen my father and brother be overweight, and while I was never fit I took for granted that I was always a little smaller than them. Now that I'm older, I've realized the weight needs to come off for my health and to enjoy more time with my family. The problem I have is staying motivated, I always end up falling off after a month or so. I'm hoping that some of us could band together to stay motivated, anyone with similar goals? If you'd like to, anyone can feel free to add me, I'll give whatever advice I can and try to motivate others too. Good luck!
