Someone says to me "I want to be as organized and productive as you are." I think, yes it's true, I'm really organized and productive. It's equal parts personality, compulsion and hands-on training as a stage manager as part of my education.
Here's the thing, wanting to be more productive is like wanting to lose weight. You can go on a lifehacking, inbox zero, no carbs diet that will do for a while, but in order to achieve long-term success you really need to commit to healthy habits and changing your behavior.
