Creator of Ruby on Rails, co-creator of Basecamp (née 37 Signals), from not having a driver's license until 25, to 4 podiums at Le Mans, angel investor, public speaker, writer and entrepreneur, David's been uber-successful by any measure.

But rather than  to burning the candle at both ends do reach his goals, David's approach to the 21st Century is aptly summed up in his latest book, "It Doesn't Have To Be Crazy At Work", a follow-up to "Rework" and "Remote: Office Not Required ".
