From No One Would Listen: A True Financial Thriller, by Harry Markopolos (the Madoff whistleblower):
"I had established the one-third rule: For every three hours you spend at work you have to spend at least one hour outside the office on professional development. That might mean reading material that might improve your life, but more likely it meant social networking [TP: this from a diehard quant!!!]. I encouraged Neil to take advantage of the pub culture in Boston, to go to professional association meetings, and to go to dinners."
I love this!
How are you doing on "the one-third rule"?
NB: While I believe that emerging "social media" is incredibly powerful, there is something about a pub.
