Checklists.
I had read Atul Gawande’s book, Checklist Manifesto, around a year ago. I started using Checklists vigorously after reading the book. That made me highly effective as well as efficient.
Over the months, my brain, mostly resistance, convinced me to let go of the lists and trust the brain instead.
The results have been much less than optimum.
It makes sense to free the brain of stuff, whether it is repetitive in nature or one-time.
A brain, free of the burden of remembering, becomes a power-machine.
