From Richard Branson’s blog.

Imagine you get up for work tomorrow and instead of grabbing your briefcase you grab a backpack.  You throw a phone, address book and notebook into the backpack.  Don’t forget a pencil.  You also pack a swimsuit and your iPod.  The only thing left to do is hop on a plane, train, car, horse or yak and get far away.  From your chosen destination you get to work for an hour or two.  You accomplish two or three tasks that moves one project forward.  Then you dig your toes in the sand and chill out.  Why not make that happen?
