Problems interest you, and trying to find solutions for them is often your obsession. You're resourceful and take creative approaches that save you or others time.

The pursuit of any worthy enterprise begins with a question. You want to know the why of things, not just the what. Then you ask yourself how you could improve it. You don't hesitate to get started, even if it's in a small way.

Abstract things, mechanical things, social things, physical things, new business models, a new heuristic or rule of thumb, whatever. You want to produce something of value for yourself or for the world at large, not just be a passive observer.

You don't see any benefit in being easily discouraged by others: you just keep doing your thing. Persistence and determination are often more important than intelligence, though you have some of that, too.

You don't mind change because you know that's how the universe works. You learn from failure, but you're also okay with your idea ending up very different than how you imagined it.

When you see what others don't see, you're a free thinker who doesn't mind that others might consider you a little different. Most good startup ideas seem a little crazy at first, a normal brain wouldn't really be able to think of those things.
