If you cut your work hours in half, I'd guess your remaining work hours would be more productive on an hourly basis. There are probably all sorts of things making that a challenge to accomplish, but we shouldn't be surprised we see those results in a context that encourages it.
Getting to that is the aspiration, don't get me wrong. At present however I'm in year 3 of bootstrapping a consulting/product startup - so every quarter is still somewhat existential.
The sooner we're reliably profitable, the sooner I can escape the hamster wheel.
