I'm going to recommend vegetarian, not vegan.

I ate vegetarian for about 11 years, only recently adding meat back into my diet (but that's a topic for another day...)

It's not hard to be a vegan at home, but unless you live someplace where vegan restaurants are widespread, you will find it very difficult to have a social life. The menu choices for vegetarians are already quite limited in many restaurants, vegan way more so.

Also, unless you have many vegan friends, it's hard to eat dinner at a friend's house or attend a potluck (unless you only want to eat what you yourself brought along.)
