Day 12 - What's something you worry about for the future?

Thought about this for a night and decided that something i worry about for the future would be my career. Not sure if i've mentioned it before but i've always wanted to be a vet when i grow up. 

Whether or not i can become a vet, it all depends on my results (biology). But apparently, my results are not really very good, so....... I've no idea what to do if i can't be a vet. :-( Have been worrying about this for quite some time but i still have no idea what to do about this lol.
