How to become a vegetarian
It made me
ecstatic! 
"To be fair, it took me 7 years, because that's how old I was when I decided to stop eating meat."
How I did it: I'm 24 now, and I haven't eaten meat since I was about seven years old. I think that was right around when I figured out what meat was and I couldn't see a big difference between my dog and cows (I mean a big enough difference to justify eating one and not the other). The health benefits are astounding, as is the (lack of an) impact I know I'm making on the planet. I'm so proud to say that I'm a vegetarian.
