It’s pretty simple: I can probably squeeze out any number of hours if I’m thrilled by the work. But few or no employers are going to manage to motivate me to do it because as Carmack says “my goals don’t align with my employer’s” or perhaps better put: my employer’s motivation doesn’t align with my motivation. So yes I’d be as effective with a 30 hour week as a 40 for most jobs. And I totally agree with Carmack: it’s *mostly* a motivational issue. But perhaps that’s a sign I we should just hire more people, pay them 75% to work 30 hour weeks.
