well.... if you honestly don't WANT to lose weight then I wouldn't even bother trying... it won't work...
however, getting your mind made up should be the easiest part - just decide you want to look better, feel better and overall BE better (i know - bad english!)
The not so easy part - watching what you eat & exercising.
If you aren't ready - then re-evaluate yourself, how you feel, and your health level perhaps that'll give you a little kick in the pants
I'm pretty healthy, I mean besides being fat

but I'm not sick or anything - I'm nowhere near diabetes or any fat-related diseases/illnesses. I have low cholesterol... I'm just effin lazzzzzy.
I recently decided that I want to lose weight because I'm tired of being disgusting!!!!!!! I'm tired of being and looking and feeling lazy - like all I want to do in my spare time is eat and sleep. I want to do things! I want to be able to run up a hill without feeling like I'm gonna keel over dead! I'm tired of having to opt for baggy pants cause my fucking legs are huge and disgusting!!! I'm tired of being self conscious when I walk into a room. I'm tired of not going swimming because I feel like a naked whale.
So- that's my motivation to get my shit started lol. Sorry I'm so chatty....
