There are't many attributes more important than curiosity.
I mean a deep, intense curiosity about how things work. How people tick. Why the world is how it is.
For example, the laptop I'm typing on, a MacBook Air: who designed it? What software do they use to design it? What training do you have to do to become the sort of person who designs laptops, anyway? Once it's designed, how do they make it? What material is this? How has it changed from the first generation of this laptop?
I don't know the answers to any of these questions, but I want to find out. More importantly, I want to be the type of person who wants to know more. I get intensely frustrated when I hear people say things like, "I'm not a numbers person," or "I'm not good with technology." These are self-limiting beliefs that should be replaced with phrases like "I like learning news things," or "I get curious about topics I don't understand."
Knowledge compounds. Might as well get the ball rolling.
