I don't know if I made the right choice

I study architecture (first year), but to be honest I don't really want to be an architect. I know more or less the reality of working as one and I can't see myself doing that. Ideally, I want to teach windsurfing (I started working as an instructor last summer), but I need some sort of backup in case I won't be able to do that anymore. So I don't know if choosing that degree was a good decision, but I already spent too much money on drawing lessons, materials for classes, etc. Also I know that no matter what other degree I'll choose, there will always be something about it that I won't like, so I probably should just finish what I started.
