Whatever you are doing—sorting your laundry to prepare it for washing, working out at the gym, doing research for your work, etc.—try to place a portion of your attention on the next fifty or 500 times you will perform the same action. Ask yourself whether there is a way you can optimize something now that will make it easier the next time you do it.
For example, Tool 1.7: 🏛️ Getting Things Done contains a discussion of doing weekly reviews with yourself. When you do these reviews, you’ll probably create a weekly checklist of items to go over. To apply the Meta tool here, each week when you review your checklist, take a moment to ask whether this is the best checklist for you, or whether you can tweak it so that, next week, it will work better for you. A lot of the time you won’t find anything to improve but, when you do, the benefit will be worth it.
