I met a lot of people that, even though they have strong reasons for being vegan or vegetarian, or even work saving or helping animals, etc. have failed to follow their principles and ended up including meat again.

Almost every vegetarian or vegan person I get to know has moved to vegetarianism for the same reasons I did (I'm moving in as well):

 - Ethical reasons (i.e., not eating other animals)
 - Trying to stop animal suffering (defending animals rights).

**But, are there reasons besides the ones listed above?**

I'm not saying they're not great reasons, which I think they are, just trying to find out all other reasons.
