@TeamYouTube I rented a movie and only realised that I had purchased the French version instead of the German version after starting to watch it. It doesn't let me request a refund. I only watched a few seconds. It isn't a big charge but it's shocking that a refund isn't possible

You can do an awful lot by writing down what happened to you and thinking it through.

You are not anxious, you just have too much free time to overthink things, mostly because you don’t act enough.

A lot of former drinkers now identify as non-winery

People with a lot of self discipline don’t actually have more willpower.

They figure out how to alter their environment ahead of time to make it easy for them later.

So it’s not about “resisting” the cookies right now.

It’s about removing them from sight two days ago.

@rachel_l_woods The is a complex scheduling problem and requires constraint programming, mixed integer programming or specialized heuristics. I have found ChatGPT pretty much useless with problems like these and the code it writes is far inferior to what an OR expert could do.

Immer wenn ein Intercity mit 150 km/h am mit Zugfahrern vollgepackten Perron vorbeirauscht, frage ich mich, ob diese Technologie heute noch bewilligt würde, wenn es sie nicht schon gäbe.

I refuse to get an apple watch.

I don't need more notifications in my life. I need less.

90% of problems in life disappear if you simply eat healthy, lift weights, sleep 8 hours/night, have a job you love, max out your Roth IRA for 40 years, find the right spouse (and have weekly date nights), live in a walkable community, make time to attend your kids' major milesto

With the right selection criteria, you can be idle most of the time. Then when the right opportunity comes, you pounce.

6% of Americans think they could beat up a grizzly bear. Further proof of the Atlantic voyage selecting for optimism

You want to build a portfolio of deals because things you think are going to work usually don't, and the crazy things you don't think will work make you rich.

Warum die Inflation in Deutschland bisher nie Thema war?

Kann man halt nicht gendern, warum also drüber reden.

People with mental imbalance very, very, rarely get rich. But when they get rich, they get very rich.

@googlemaps Somehow "Bahnhofstrasse" in Zürich, #Switzerland was renamed to "Zinnengasse". (Which exists in Zürich, but is somewhere entirely different) This is definitely not correct. How did this happen?
