Yes, I do want to learn.

You could say it's an "inherent personal curiosity" as your therapist might. As a kid I would sometimes pick through gravel examining each stone carefully and pulling out the small chunks of quartz; I loved going to 'rock shops' and looking at all of the fossils and crystals, always got a geode to break open when I got home. Living in Seattle I'd go the Pacific Science Center, once for a birthday, and really enjoyed the interactive displays. I'd read through my dad's textbooks even before I could understand the words and when I started using the internet I'd do the same with wikipedia. Most of the jargon still went over my head, but some of the stuff stuck and I managed a pretty decent knowledge base over a pretty broad spectrum before starting chemistry/biology/math in high school and college.

Nowadays there's more to it than just pure curiosity, though. I've asked myself what is fundamentally important to myself more and more frequently over the years, and the answer has pretty much always been (loose definition of knowledge) "gaining knowledge, applying it to the world, and helping others to do the same." This is usually the result of some other questioning:

Q. Why am I here? A. I don't know. I don't have enough information to answer that question. I need to know more about myself and the world in which I live before I can even think about answering this question.

Q. How can I be a good person? -> How can I contribute to society? A. I like people who help others, aren't selfish, work hard, are generally optimistic and friendly, etc. I feel good when I exhibit those behaviors, especially helping people. To help people in big ways, you need a lot of people with a lot of information and experience working together, and to be one of those people you need to learn. Right now I'm studying to become a microbiologist and am spending most of my time learning so that I can participate in research and help expand mankind's knowledge base.

To be frank, I also learn so I can keep my mind occupied. When I'm not occupied I start thinking about how inevitable death is and get in weird moods, so when my natural curiosity isn't enough motivation and I get bored/have nothing to do I just study.
