I grew up a fat kid. Mom fed me anything and everything I wanted. As a result, by the time I was in junior high, I was pretty good size. By high school, I was 5'10 and well over 230lbs of pure fat. In gym class, not only was I the last to get picked, but the other guys would slap my legs leaving handprints or grab my love handles till it hurt. I'm a big fat pussy pretty much.
I started cutting classes to avoid being teased. My GPA dropped so low that I eventually got the boot over to the continuation high school for problem kids. I thought of killing myself many times until a teacher suggested I take my GED and go on to college. I did just that and finished two years before my class. While in college, I decided to do something about my weight. I start just running 20 minutes, 3 days a week. Then I changed my eating habits to simply consuming better foods.
Five years later following college, I looked in the mirror and knew I'd lost my weight but my overall shape was still the same (as the fat boy). It occurred to me, lifting some weight might change that.
Change like that takes months and years. It is a slow, challenging process... but it is worth it. It is absolutely worth it.
