We've been doing four-day weeks since 2008, with two offices in Australia and remote team-members in Berlin and the Phillipines. Apart from the obvious 50% more weekend for 20% less work, and the flexibility to work from anywhere, doing it this way has a less-tangible benefit: it requires and inculcates discipline and responsibility. Your attention is like a gas: it'll diffuse to fill the space available. Timeboxing your energy provides more work potential -- and your downtime is more productive too.

It's also a great talking point with clients. The 4DWW is gaining traction in the wider world: I was interviewed this week on dot-au national television to talk about it.
