Esoteric author Mitch Horowitz recently launched his Substack newsletter, Mystery Achievement, where he shared a list of 101 rules for effective living, distilled from more than 30 years of reading “nearly every major work of inspirational literature produced or translated into English.” You can find the full list here. Below are some of my favorites.

6) Be willing to clean toilets and wash floors.
20) Get away from cruel people—at all costs.
38) Look people in the eye, recognize them, acknowledge them.

My mental image of country sizes has been wrong. The True Size Of... is an interactive website that lets you drag countries around a world map to compare their actual sizes without the distortion caused by standard map projections. It's shocking to see how countries change shape as you move them — drag Greenland into Africa and watch it shrink to a small fraction of its map projection! — MF

It's been so long since I've used a portable transistor radio that it feels like advanced technology. The Prunus J-166 is an impressively capable pocket AM/FM radio for $10. It's about the size of an iPhone and has just three simple controls (tuning, volume, band switch) that make it intuitive to use. It also has a tuning indicator light, headphone jack, and battery indicator. Requires 2 AA batteries (not included). — MF

I really enjoy Broadway musicals but I rarely get to New York or London, so I was delighted to watch this filmed Broadway musical on the streams. Come From Away is a fun, sweet, uplifting musical based on a real event: after 9/11, all the planes mid-air bound for the US were diverted to a small airport in Newfoundland, Canada, where the outnumbered locals welcomed the 7,000 stranded passengers into their homes and small town. The musical celebrates the best of human kindness triumphing over the worst. It is also a touring live show and you should catch it if it comes your way. — KK
