Talk to some people who are doing the job you're after. There's often a big difference between the career you fantasize about and the day-to-day reality of turning a hobby into a full-time gig. If you love antiquing, you might dream of opening an antique shop of your own. Remember, though, it's not all about scouting out great finds. You have to deal with taxes, accounting and business licenses. For many people, it's worth sorting through the more mundane details in order to do what you love, but make sure you don't take the plunge with stars in your eyes.
This is another case where the informational interview can be a big help. Ask about the day-to-day responsibilities of the job you want and what it's like to work at that particular company. Few jobs are as fun in practice as they seem to an outsider, and getting a clear picture of your potential new work environment can help you ensure that you don't end up disappointed.
