No inside knowledge here, but another suggestion would be to keep an eye open for a school that has some sort of program to get into internships in the proposed profession, ideally as early as possible. In my extended family I have recently seen a niece go through three years of hotel and restaurant management. Then after a six week summer internship working in the back kitchen at a local upscale restaurant she decided maybe that wasn't her field. I do think it's hard for someone 16 or 17 to decided what many of these jobs really are going to be like once they are in them (heck, it happens to fifty year olds!)
