You should never do what you love. You should do what works for you. I love fishing, but I would never hold it as a job. Programming works for me. I like it, its fun, challenging, and allows for a good lifestyle. Two different things.

We love those things that bring us pleasure, we like those things that allow us to do the things we love.

Even though I'm from a technical background, I'm finding that I really enjoy the business side of things, enough that I would (and will) happily cut programming responsibility loose whenever I can find a technical CTO, or even a good lead programmer. But when there's no one you can trust with the work, and you know how to code, it's very easy and very tempting to spend an evening up to your elbows in code. It's safe and comfortable.

But if I wanted safe and comfortable, I wouldn't be trying to start a company, now would I?
