I agree with auroralily...
One may also need time to get resources together. It took me awhile to figure out what to do with tofu. I also had to do a lot of reading to come up with a menu that healthy, convenient and tasty. And again, my reasons for becoming vegetarian weren't based on animals rights.
...except I did make the decision based on animal rights. I knew about the treatment of animals on factory farms. Missleigh would always tell me about stuff if asked, but never in a preachy way. I joined PETA, and watched some video footage from farms. Not a good thing to do at work. It tore me up. I guess I'd never really let it sink in when I'd see that footage before.
I quit eating pork and beef first, because I didn't eat much anyway. The elimination of poultry, eggs, and seafood came about 2-3 months later. I, too, had to research and ask around about just what I was to eat in place of meat, where to get protein (turns out almost *everywhere*), etc.
I went ahead in my intro and said I still sometimes eat cheese and eggs as ingredients, but not in my own cooking, hoping no one would jump down my throat. So far, so good. And I don't know if or when I'll become vegan.
