I would avoid medicine and engineering, those professions take a long time and come with heavy debt, but they're also being outsourced rather quickly. The keys to the future are in building and owning infrastructure; that means tech and finance. Literally just tech and finance -- that's the backbone of every industry moving forward. They all need software, they all need money. We'll need lawyers too, but they're in the same boat with the doctors and engineers.
