As long as we are talking about Tim Ferriss, I read on his blog about Leo Babauta and his way to make habits stick. Besides from the usual tips like setting goals and committing to the project publically, he has one idea that sounds great: Commit for 30 days. After that the new habit has stuck. It is actually the same idea as behind the Scrum Shocktherapy talk made at Öredev this fall: Follow the plan and commitment slavishly in the beginning. After a while, you learn and start getting the benefits which come from following the plan, and since you have matured, you wouldn't trade away the new ways of working.
