It's not what you do, it's what you don't do

5. Minimalism – “What makes Steve’s methodology different from everyone else’s is that he always believed the most important decisions you make are not the things you do – but the things that you decide not to do. He’s a minimalist.”

And it's really difficult to show off what you've done (not done) if you're a minimalist. I worked with a minimalist at one time. People would ask me about his contribution and I'd show them a picture of what we'd designed, point to the blank wall around the picture and say "That's Fred's contribution". I think some people got the point.
