Quite a compliment, thanks. I learned this approach in industrial design school, where you're surrounded by a whole class of other people who also have their own ideas. You sketch your ideas and there is a real danger of falling in love with something too quickly and cramping to push it through. And then you realize, it only looked good on paper, or only looked good to you, or to were mistaken about its functionality, proportions, readability or whatnot.

Those who want to create great things cannot afford to fall into love with them. You can fall into love with a particular problem or question, but not with a specific solution, especially not if you came up with it.
