I get all my good ideas in the morning - when brushing my teeth or in the shower. Research has shown that you get good ideas when your mind is unfocused and relaxed - and away from distractions of any kind. I guess in today's connected world, the bathroom is one of the few places where this is still true! I also recommend you read the wonderful book "Where Good Ideas Come From.." by Steven Johnson (check it on Amazon) for a great set of principles on how discoveries and invetions come about.
