Dream life! How did you go about negotiating 4-day week at a startup? From experience sturtups have been a "6 days in a 5-day week grind". Seeing a 4-day week is refreshing!
I just made it clear from the beginning that that was what I was looking for. They had no issue with it.
It does feel like 5 days in a 4-day grind sometimes, but at least I get the time to indie hack.
