Wish you all the best!
And, of course this cannot be your own motivation, but its true nonetheless, with this initiative i am sure you will inspire others to also get to work on their weight. Myself included (although waiting to start with that ujntil i move back to Europe, runing and sporting in this heat wouldnt be a good idea as im focussing on survival in shanghai atm.)
Wish you all the best and looking forward to your progress!
