Best career for me..?

Yeah, you are right money isn't the most important thing. I understand that bills are all ways there but 50k/year (UK) is way more then one needs to live on. I would much prefer to enjoy my job rather then have lots of money. Although of course Ive never really had a fixation with materialistic things so money doesn't really bother me. If you want to be a Vet you should go for it regardless of the money.
