Whilst I'll confess to slight jealousy over Ryan's 4-day week, and note that despite less being more, he admits to getting less done:

"Now that we’ve been working a four-day week for three months, we’ve realized that we can’t always get the same amount of work done. Let’s face it, there are only so many hours in the day, and if you work fewer days, you will inevitably not get as much done."

...his practical tips are spot on. Every month or two I administer myself a private kicking and cut down on news reading, email checking, turn off IM, and attack my Lists of Stuff To Do...

...and he's right about that death-bed thing you know...
