I would go for whatever could make me the most money with the pure skill that they teach in school. In most professions, it seems like you need either some talent at sales or self-promotion or just luck to be successful, in addition to whatever skill you supposedly have. I think that maybe being the world's greatest computer engineer or something like that would probably get you paid millions without having do much other than be amazing at what you do.

My initial thinking was cardiac surgeon or something like that, but on further reflection I think that is about the worst choice possible. You have this amazing skill, but what do you do with it? Do you have to go to medical school and get easy As before you can get licensed to use it? That would really suck.
