When you struggle with a problem, that's when you understand it...if someone was really the person that solved it, they'll be able to answer multiple levels, they'll be able to go down to brass tax.

I can't even judge what's difficult and what's not. The root of most problems is missing knowledge, and once I completely understand something, it seems clear to me.
