I want to be a vegetarian but.....?

.......it seems like too much work. before u say something like are u doing this because your friends are im not. i read a book about being a vegetarian and at first i just wanted to read but after a while i did more research and began wanting to be a vegetarian but it seems like a lot of work. eating different food, substitutes for old foods, and giving up foods i love. how did you get over the foods you loved and how difficult was it? how long hav e you been a vegetarian or vegan? last question is tofu good? (im 13 years old)
