I've been working from home for ~9 years. We live a short distance from town, so I use small grocery runs for about the same purpose as you were using commutes. Drive for 15-20 minutes listening to a podcast or thinking, do something useful, then drive back.

Hard agree on a clear distinction between work life and home life. I require an office in the home with a door that closes. When I am in the office, I am working. When I leave the office, I am not working. The closed door separates my work life from my home life.

My kids are trained not to come into the office, and my wife respects the boundary and messages me instead. I don't work from the living room or dining room. (I've tried, and I can't do it anyway, I become nearly useless to both the family members trying to talk to me, as well as my employer.)
