Why not do both? One of the great things about flying is that as you get some seniority (which you won't have for years) you can work at other things, too. Some people will disagree with me, but I know plenty of professional pilots who have second jobs and careers. If money is no object go to law school and fly at a local airport at the same time. (The advice from SWAjet about networking is great). Plus, airline pilot employment is very cyclical, especially for the passenger carriers. Cargo has so far been immune, but who knows about the future? Always best to have something in your back pocket.
