What an awesome answer - thank you for taking the time to write it out.I wanted to look better in clothes (and out of them. hehe), I wanted to be fitter, I wanted the freedom to be able to wear a fitted shirt or t-shirt without being insecure about man-boobage and my belly, I wanted to be able to engage in Parkour, I wanted to dance without being embarrassed about 'wobbly bits wobbling', I wanted the stamina to be able to withstand a long-haul flight (with multiple connections) without being totally wiped out at the end...
I love seeing and feeling the changes that occur. I like the seemingly boundless physical stamina I've got. I like that I can decide, on a whim, to move very heavy furniture, by myself, while barely breaking a sweat. I like being able to wear whatever I want to without being insecure about unwelcome 'bumps' here and there. Also, the compliments and appreciative looks certainly don't hurt either.
I never want to go back to what I was and still feel ashamed that I let myself get to that. I feel immense shame that I used to scoff stupid amounts of the worst forms of junk-food with nary a thought as to what I was doing to myself, shame that I'd sit on my ass all day at the office or at home and engage in absolutely no unnecessary movement, shame that I took solace in food and my novels (simultaneously) whenever I was down/stressed (the novels aren't the shameful part).
A lot of my motivation to live a healthy lifestyle (for it is an all-encompassing way of being) comes partially from my fear that I'd revert to what I was and mostly from my perfectionist tendencies. We have a saying in Swahili that goes "Unakula ngombe mzima na unabakisha mkia?" Roughly translated, it means "If you're going to embark on something, see it through till the end." (how J). I've decided to live healthy and I'm going to go the whole hog, so help me God.
