You want to be a master at efficiency? Stop depriving yourself of things that seem to save time, but actually slow you down.
If you’re at peak performance, you can do more in 25 hours than others can do in 60.
So once you rearrange your work day to give precedence to the more important, but less urgent items in your work day, so that your input rocks, the next job is to tighten up your output.
I’m not kidding when I say that performing at my peak effectiveness, even as a spoonie, I not only shortened my work day and work week, I got a lot more done.
