Take a Nap
I have taken afternoon naps all of my adult life. I started in college in between classes. I lived in a dorm on campus. Sometimes I slept in the library.
My boss at my first full-time job was Leonard E. Read, founder of the Foundation for Economic Education. He took a nap after lunch. Therefore, I knew I could get away with this, too. The upstairs at FEE had bedrooms. I used one for about 30 minutes every afternoon.
I am efficient, but I need my afternoon nap. I have been self-employed since January 1, 1977, so I get to set my own schedule.
It turns out that there is now evidence that naps increase most people's productivity.
If you have a desk job, take 15 minutes to eat a sack lunch -- cheap -- and put your head on your desk to sleep. Use an inflatable pillow and earplugs. Put up a sign, if necessary: "This is my lunch break."
