Are there not problems in your life, or community, that you feel could be solved?
I often find that momentum leads me to want to stay home, and do nothing, but the end result is unhappiness. You have to suffer the slight discomfort of starting things to enjoy the long term and greater joy and pleasure of building community, creating something, improving something, or learning something.
You say you find chemistry, mathematics, art, and programming interesting. What about those activities make them interesting? Perhaps you could study chemistry and become a chemistry teacher. I've heard artists (In the broad sense of musicians and writers as well) say they aren't always inspired, but they get up, get set, and start anyway and see what happens. I think there are probably plenty of ways to learn programing that are "gamiefied" so they don't "feel" like practice.
