[…] you have to recognize that most of what you do is wrong. You can only get to be right by being wrong. You’re wrong nine times and then the tenth time you may be right. And if you haven’t got the nerve to be wrong nine times, you’ll never find the tenth. So you just go in, and you blunder around, and do this stuff until it starts to come right.

— Christopher Alexander, Lecture at the Institute of Architecture in London, 1995
