As founder: about 12 hours, I take about 4 hours total breaks in the day to swim and often an hour or two nap in the middle, nap required because two 6 hour chunks is quite strenuous

This is not rigorously followed - sometimes 3 hours then an hour break then 3, sometimes 6,

I eat when I’m hungry and I sleep when I’m tired, I don’t have fixed meals or fixed schedules

First ~6 hours normally admin, emails, proposals, reseller support, mentoring juniors

Next ~6 hours is 100% coding

Work from home so no commute, nothing else to waste time on

Work 6 days a week, Sunday’s reserved for rest, reading and research
