Ignoring the Future: While you shouldn't make your choice solely on an occupation's appearance on a "best careers list," to ignore employment outlook is careless. There's a good chance you don't have a crystal ball that can tell you with certainty whether an occupation will grow, or at least be stable, during the course of your career. However, you can do more than hope for the best. You should consider whether a career has a promising future before you begin to prepare for it. You can at least eliminate something if its future looks bleak.
