It depends on the course, and the reason you're in science. If it's for the money go into business, or supplement with managing classes so you have something to fall back on. You can make the big bucks, but you have to investigate, and you have to work really hard. People without passion will tend to fail in a science-based career. However, it's still worth a shot, and can lead to many opportunities. Though, I wouldn't suggest doing anything you don't like. You won't be as good at it, or as committed.
