First and foremost, I'm a decorator and product designer. Everything I do, the television shows, the books, that comes from the design work. It's what I love.
Design work doesn't just satisfy requirements, it elicits them.
Don't worry about people stealing your design work. Worry about the day they stop.
Darwinism may be a fine theory in other contexts, but in startups, intelligent design works best.
I was a cartoonist when I was at university, but I decided to go into movie making knowing that I could still draw by doing movies, design work, story boards, and such.
Designing is my hobby. If I didn't do what I do for a living - at some point when I don't do this for a living - I'll probably just do design work. I love finding really special pieces of furniture.
