As expected, becoming a father cost me a lot of free time, but when I started working from home I lost my commute (usually walking, sometimes biking) and that was the one that really stung.
It was only a half hour or so each way, but I used that time to catch up with friends, listen to podcasts or music, or just let my mind wander. Now I have to really make an effort to carve out "me time," and with the Covid time tax it's really difficult.
