I do what I did in the office, minus the ability to socialise, have small chats, brainstorm effectively, and interact on a personal level.
I don't need to go into the office to do 70% of my work, but the rest of the time I do meet clients, go to industry events, host round tables/workshops. the key element that's missing from working from home is spending time with people. Doing it virtually is ******* tedious.
That said I'm spending 2 days a week on average popping into town (well after 1.5hrs or so of travel time), to see clients, businesses, friends and colleagues, and unsurprisingly, get a lot more done as you can have those nuanced conversations and do those connections that you can't do on a zoom call.
