Digital hygiene
My first Computer was a Medium MT5 from Aldi. I loved it, playing Stronghold and Counter-Strike. To communicate with other players, we had forums. I used the same repetitive email over and over to join those forums, resulting in my email being exposed in many data leaks. I didn't mind first, but ever since seeing someone trying to log in to my not used goodreads account, I thought maybe instead of exposing my real email address, I should get a little more Digital Hygiene.

Starting with email, I decided to use ProtonMail with a custom domain. The reason for a custom domain is obvious: if I want to ever change a provider, I could switch to a new one.
Notes
standardnotes.com does the job; I needed a little sync. It works perfectly.
Work/Life
I think this one I should work more often, I'm using a Mac for anything, personal things. But I use Teams, etc., for communicating whenever I need, I'll try to separate those things to keep more focused on Personal Tasks and job-related tasks
