I also believe real ideas select their host. Almost all my good ideas came to me and asked, persistently, and from many different vantage points to choose them. And I have learned 1) to pay attention and let them in, asking "What do you want to be when you grow up?" and 2) Never go it alone. Be in an ongoing relationship with your idea. Ask, see, play with, anger, persist and what you realize together will make a difference to the world of ideas and the world of reality.
