I don't remember ever seeing a careers officer at my school, which probably wouldn't have made any difference. I didn't know what I wanted to do at 17, I still don't know what I want to do at 47, and I've hated every job I've ever had. More often than not because of the bellends I had to work with rather than the actual job. I'd even hate to be a full time musician. Getting dragged all over the place and having to put up with the great unwashed doesn't appeal to me at all.
