First and foremost, I want to be healthy. I don't want to put myself at risk of certain health conditions in the future, and I want to have energy and verve in my life (including mental clarity) which I know comes from fitness.
I'd like to feel better about myself too. I've always, always had self-esteem problems and, while it's been awhile since I've actively hated myself, I'm finally getting to a point where I don't just tolerate me, I actually like who I am. I'd like to get to a point where I don't just tolerate what I look like. (Although I'm aware that's as much psychological as physical)
Finally, and less importantly, I'm a university student. I don't have money pouring out of my ears, and I've put on a lot of weight since I've moved out of home. I don't fit a lot of the clothes I came to this country with at the moment, and I'd like to be able to get back into them rather than living with 1/4 of my wardrobe or needing to buy clothes. (Although I would like some nicer clothes as well and am saving to get some when the weight comes down)
