Work is gas.

“When I was at MetaDesign in the ’90s, there were regular meetings with a dozen people and everybody had to wait for me because I’m the boss. Then one time, I worked out the math that if I’m five minutes late and there are 12 people sitting there, that’s 60 minutes. And if every one of those people charges $100/hour for our client work, then I’m wasting $100 by having people wait for me for five minutes. I know it doesn’t quite work that way, but it does add up over time. From that day on, I realized I could be five minutes early.”
