I once had a conversation with someone in which I explained that most people find me boring. He corrected me by saying that it's not that I'm boring, it's just that my interests lie outside of what most people are interested in. If I met someone who shared my interests, they would not find me boring. So it's a matter of perspective.
There is something that excites you, it just may be something that doesn't excite the people around you. If you take a little time to think about it you should be able to figure it out. It's that thing that causes you to become excited when you think about it. So go think about it for awhile and while you are doing that I'll just be sitting here being boring.
