Every productivity article assumes a baseline level of motivation that you don't have. "Just wake up an hour earlier!" Sure, and just be taller, while you're at it. Here are productivity hacks for people who find the concept of productivity itself exhausting.
Don't aim for inbox zero. Aim for inbox under-a-hundred. Don't plan to exercise for an hour. Plan to stand up. Don't organize your entire closet. Pick up one shirt from the floor. The productivity industry sets the bar at Olympic height and then calls you lazy for not clearing it. Set the bar at ankle height. Clear it. Feel like a champion. Repeat.
David Allen's Getting Things Done system says if something takes less than two minutes, do it now. This is good advice that nobody follows because checking if something takes two minutes takes two minutes, and then you're four minutes in and you might as well check your phone. The honest version: if you can do it before you finish this sentence, do it. Everything else goes on a list you'll look at eventually.
When you're avoiding one task, you'll do almost anything else. Use this. Put the worst task at the top of your list and then "procrastinate" by doing everything else on the list. You'll clean your desk, answer emails, file your taxes, and learn conversational Portuguese, all to avoid the one thing you're supposed to be doing. You're not being lazy. You're being strategically avoidant.
Some people are productive at 6 AM. Some people are productive at midnight. Some people have a solid forty-five minutes of productivity around 2:30 PM on Tuesdays. Whatever your window is, protect it. Do your most important work then. Do your least important work — which is most work — whenever. The hack isn't doing more. It's doing the right things during the brief window when your brain cooperates.
