Despite having previously thought that (given total time spent) I should try optimizing toothbrushing, and even flossing specifically, it's only today that the thought occurred to me that I spend way too much time and mental energy trying to floss in a way that conserves floss, compared to a brief search online to find cheap floss that I don't mind wasting.
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!
