In retrospection, this method can't be universal. Someone pointed out that:
Some people can force themselves to awake, sleep deprivation or not.
Some people oversleep.
Group 1 doesn't use alarm clocks. Group 2 must use them.
Piotr Wozniak would argue that people who oversleep were sleep-deprived to begin with -- you couldn't sleep 11 hours a day arbitrarily long, eventually you will have fully paid back your sleep debt, and from that point on you'll only sleep about 7 or 8 hours a day. (My experience mostly agrees, though in my case at least physical energy seems to matter more than mental energy in determining whether I'll fall asleep.)
This is the public group instrumental rationality diary for Christmas week. It's a place to record and chat about it if you have done, or are actively doing, things like:
Or anything else interesting which you want to share, so that other people can think about it, and perhaps be inspired to take action themselves. Try to include enough details so that everyone can use each other's experiences to learn about what tends to work out, and what doesn't tend to work out.
Thanks to everyone who contributes, and I hope everyone is having a nice holiday!
