GTD, 18 minute plans, organized folders… none of them work as well as you'd like.
The reason is simple: you don't want to get more done.
You're afraid. Getting more done would mean exposing yourself to considerable risk, to crossing bridges, to putting things into the world. Which means failure.
The leap the lizard brain takes when confronting the opportunity is a simple formula: GTD=Failure.
Until you quiet the resistance and commit to actually shipping things that matter, all the productivity tips in the world aren't going to make a real difference. And, it turns out, once you do make the commitment, the productivity tips aren't that needed.
You don't need a new plan for next year. You need a commitment.
