If you want more free time, freelance IT support is good, if you have clients. Healthcare industry pays well because everyone wants to live forever - and is willing to pay for it. It's not quite the same for computers, since you can find any geek from a squad to help you fix yours.
My mom asked me what I wanted to do when I graduated HS; I said, "build computers." She said, "Sorry, Michael Dell beat you to it!" Before I decided on computer engineering, I was very interested in computer hardware, which meant electrical engineering. Then I found out how hard it was to get a good hardware engineering job, so I switched to software.
I think it's great to follow your heart and dreams, but you gotta pay the bills. The trick is finding a career that will afford you the time and money to support the hobbies you love, without driving you insane.
