Latest from the "Design Methods" chapter of my up-coming-sometime-soon-really book, Alice Through the Proscenium:
Happy Accidents – Serendipity again. Ideas can arrive accidentally. The trick is not so much in having that luck as in recognizing it. One 1980’s internet entrepreneur said his secret was surrounding himself with smart people doing lots of different things; in that happy chaos there had to be one good idea - his job was to see it. Have lots going on in your work and life, so that in the busy mess good things can happen. Then spot them! Luck requires some chaos.
