So here's my new motivation for keeping pace on this weight loss journey.  As a Taekwando student, I test for a new belt every two months.  Within the span of this weight loss challenge, I will have gained 3 new belts.  The belts will serve as motivation to lose 10 lbs by the time I receive my next belt.  That's 10 lbs every 2 months.  That doesn't seem too unreasonable, now I just have to put forth the effort!
