For me, I have a ton of different motivators.
1) I am going to be 29 in a few days...which is going to put me at 30 in just over a year. I want to look good BEFORE I turn 30.
2) I want to have another baby...hopefully be pregnant around the time I turn 30. I have had 2 c-sec and desperately want to try for a VBAC with #3. Better health may help me be able to do that...who knows???
3) I am so stinkin sick of dodging out of pictures. I want to feel ok about having pictures taken with my children. I barely have any at all with them...and I don't like the few that I do have because I can't look at them and remember the fun we were having...only can think about how rediculous I look.
4) I HATE plus sized clothing. It is poopy and granny! Now...I am pretty conservative in dress (I go for skirts knee length or longer, no cleavage, stuff like that). That isn't going to change just because I get thinner...it's just me. I don't like the whole 'flaunt your body' kind of thing. I don't feel the need to have men drool over me and have other women jealous. But I still want to be able to wear cuter clothes! I want to shop for the same sizes as my sisters and friends when I am out with them instead of just hanging out and saying 'oh...that is cute' but not even being able to pick up something and try it on. I want to be able to find cute clothes! No such thing in the plus-sized world.
The list go on and on...sooooooo many reasons not to be overweight!!!
