Depends on the person. I find that it's extremely satisfying to figure out a tricky problem on the way to that end result - to struggle with something for a bit, then finally fix it or fully wrap my head around it. So to me, it's a mixture of both. What I want is the end result, but in the past sometimes that came with thinking in the shower about an approach... Or a wild thought while going to bed that makes me jump up and grab my computer.

That doesn't happen for me anymore to the same degree.
