I read an article found on Lifehacker (http://lifehacker.com/5932586/make-work-feel-less-like-work-with-the-8020-rule) that resonates with me.
The funny thing is, most of us are already doing this anyway, albeit not in the way we think. The majority of the american workforce steals time for themselves every day. In fact, certain working methodologies allow for this and assume that the “ideal” workday is somewhere between 75% and 81%. True indeed, some of that “extra” time is given to meetings and what not, but on average at least a full hour is viewed as non-productive, every day.
