I have an inner compulsion to always accumulate more and more information. I never feel adequate in knowing, and am always uncertain about what I know, so I absorb data from as many sources as possible. For example, it's really easy for me to read all day, research on the computer all day, or go to the library all day, where I have no external distractions. Instead, I can focus internally on a problem, almost to the point of obsession, where everything else fades away but what I want to learn. It's always an endless search that's never fully satisfied.
