For me thinking in terms of Failure around weight is natural... however, I found that moving away from that thought process (easier said than done) was helpful. I think in terms of tools... my band is one tool. My exercise and mental plan/strategy 30 seconds to Victory is another and critical. My sister has also used it and is down 180 lbs so far - I have band, see my profile. Let me know if I can help. You may find my sisters blog helpful http://www.300poundsdown.com
