Jack White (if I went to one of his concerts I'd scream like a 13 year old girl) has this theory that anything needs at least three parts to hold up, like a stool. Like If you have a fantastic burger, amazing fries, but your soda is flat. Or maybe your car interior has two colors–that third color would really make it pop. It's a low enough number of things that you can think a lot about each of them–but without getting bored.
So how does that plug in to whatever you're doing?
