Oh.. Oh no..
Keep in mind, the popularization of the concept of a mid life crisis was a tiny piece of a man's career that he thought was useless and unexciting. Sound familiar?
I'm older than you, and been through similar, and my life radically changed later (for the better now, I'm lucky), so things are different for me, but, my advice from me back then:
Excitement != Change
You need something new in your life. Your wife probably does to. If you feel like you're in the right life situation, with her and yourself, do your best to throw yourself into something. Figuring that something out? Really hard.
For me/us, ripping the seats out of a minivan and building a folding bed, running water, etc, and using it to travel around to local trailheads or breweries and camp in random locations many weekends was just the thing. Even the experience of traveling to get a good deal on the van was new and fun.
Excitement doesn't always come looking for you, but it's still out there.
It's about the changes in microgravity, extreme G and light. Pure guess, but it's perhaps testing for travel as much as inhabitant.
Debian. Used to use others but realized they all just added crap I didn't want, or could add myself with a simple script.
I was a Slackware then Fedora, then Ubuntu as my daily drivers (whipe trying other distros, or Kali for specific purposes) before settling here.
Take the location limit off. Way too annoying for common OSM updates.
Same. I can barely even tell what "good" Ubuntu brings to the table other than the task bar icons, which I just add in with am extension.
We simply don't need Reddit users. We need Lemmy users who desire to start communities. Lemmy is Reddit 10 years ago, and that's just fine.
I've been working with some smart people on something to hopefully become a "federated account" that can be used with any service, and is 100% compatible with OIDC, so its easy for systems to implement as the authentication vehicle: https://fedid.me
Just presented it at IIW and interest is building thus far, so my hopes are high 😉
Go on a vacation with a dumb phone. Make sure there are tons of active activities to wear you out. Bring a friend if possible who will do the same.
Before you leave, set up some form of blocker/parental controls and have someone you trust set the passwords.
All good suggestions, but mine is: Start with something redundant.
Do you use Google Drive? Set up Nextcloud and use both for a while.
Also, decide on user management first. It's way better to have a central system for managing passwords/etc. Personally I use an Active Directory based off Samba4: https://github.com/Fmstrat/samba-domain because it's got LDAP and expandable with Keycloak to OAuth and OIDC. This may sound overwhelming, but once you learn what they are, its fairly straight forward.
Yup. No-one (non techie) needs a specific Linux distro. They're all easy to use for normie activities once installed.
