It is usually illegal to give legal advice or represent someone without being a lawyer, so this disclaimer is meant to protect yourself against claims that you're doing so. I think.
You can use a bank like Wise which lets you have accounts in many currencies for such bank transfers. Fees between their accounts are quite competitive (I used them many times in the past).
Spotify stopped improving about 8 years ago, and has only been enshittifying since. This allows for even more of that. I miss having a decent music app.
They usually block via DNS, so it's pretty easy to circumvent by using alternative DNS servers such as 1.1.1.1 or 9.9.9.9, or Tor (which you sometimes need for books that have been DMCA'd)
Last time I checked the logs after an update, what I understood had happened was that the installer was installing the new files one by one, and logging each one of them. Which is a lot of files. I've no idea if this is still done this way, but I suspect it's part of the reason for the slowness.
Any career path that requires strong cognitive skills is susceptible of being damaged due to brain fog, not just mathematics. Will there be fewer people doing all of them?
It works though, because the bank can still receive the transaction and reroute it appropriately. It's pretty common in the EU, especially with things like road tolls that don't check the card validity in real time.
That "everything else" includes eating, commuting, grocery shopping, and all the other non-fun stuff we must get done. And that's considering 6h/day of sleep, which is insufficient for most people.
Salaries are the minimum figure that allows companies to hire the talent they need. If they go too low, people just start looking at other options (i.e. starting up, freelancing...). If you're easy to replace, someone will do the same for less, if you're difficult to replace, it'll be expensive to do so. Etc.
That sense of exhaustion eventually goes away after a few months working full-time. That said, even now I feel the amount of interesting stuff I can do on a week day after work is pretty limited -- not just because of time, but because of brainpower. And you can't really use every weekend either, or you'll burn out fast. So a) make peace with getting a lot less done, or b) find a way not to work full time.
When I try to work on my side projects in the evening, I often feel the same distraction / anxiety effect. The way I handle it is to tell myself it's ok to get some rest and do things that are not productive, and try to keep away from the computer for one or two evenings. Often after that I find I can concentrate better again. We need idle time to structure our thinking process, after all!
