The pandemic has been bad in many ways but during the first lockdown i got into the habit of a nightly hour long walk. It's been a really great thing for my mind space after work each day.
Yep, wonderful thing indeed. Unfortunately it means selfishly spreading whatever plague-of-the-moment around, so some places instituted a 8pm-5am curfew to prevent these inappropriate habits from forming. Vic, AU had curfew for 5? 6? months out of the last two years. Worked wonders for some people's mind space.
Try meetups, concerts, trivia, etc. You'll get further in your endeavors through absorbing info irl rather than trying to create from nothing.
