When I was a teenager and in my early 20's, I was extremely skinny. I started lifting around age 22 and grew pretty big and pretty fast. Then I stopped til my late 20s and got pretty flabby and gross. I bought a book at Border Books called "Body for Life" and made up my mind to never be fat and disgusting anymore.

People respect you a lot more when you're big and and in great shape. People don't mess with you because they're scared due to your size.
