Thanks to @copyblogger for the article referenced below.
While the article is about writing copy, I think it's relevant for all of us today. That said, in a world of generational interruption, the real message for our kids becuase is really about focus. No IM's, txt's, tweets, facebook posts, email (yea like kids know what that is), selecting another song. As yoga would say - diversions all these are, real productivity killers they will be when you are trying to get something done.
I used to complain at work about all of the interruptions. Every time someone poked their head into my office unannounced, there followed a period of reset. The time it took to get back into what it was you were doing before the interruption could be as much as 20 minutes - otherwise lost. Even when you closed your door, set your phone to do not disturb, other people's expectation of email being instant response required prompted the next interruption.
I love the 33 minute timer and small set of rules in the Schwartz system. Just set a time limit and focus on what you are doing while you are doing it. Imagine putting that to work for you. Imaging that working for your teenage. I can only imagine.
