The most important thing I learned in 2012 is that it is OK to sit and do nothing.
Most people would tell you to get off your butt and do something productive. Stop wasting time. I don’t buy it anymore. You do not have to be going, going, going all day long. Sometimes it is fine to just be. Just sit there and think. Or don’t think.
I am not saying to be lazy. You can’t take a break if you have not done anything in the first place.
But you should never feel guilty to just be.
