I really feel that I have an interesting mind. Yet I feel that it is only interesting when I can follow through major research projects and organize and discipline my ideas. So maybe other people have minds as interesting, in theory, but it never comes out because they never have a chance (or the ability) to develop ideas in that next step. A lot of people's minds are simply not that interesting, and this is mysterious to me.
There are several types of people: those who can find interesting material, but can never quite do anything with it. Those who follow dull paradigms set by other people.
