W.r.t the "imagine your day is 6 hours long, then you could fit 3 days in one" 'advice'.<p>I haven't read the original article, and won't, but I'm imagining what they mean by that is 6*3=18 (+6 hours of sleep = 24).<p>I have two jobs right now; primary gig + ~10hr/week contracting, both tech. I'm actually a big fan of this model of thinking, though not as extreme; I'll elaborate:<p>Classify 3 days a week as "hell days"; 9a-6p job1 + 7p-9p job2. Tweak the numbers as you will for your own situation, but critically, for every hell day there's a heaven day: Monday you're working 12 hours, but Tuesday you're only working 6 hours, and alternate.<p>I've found this model to work well, even when it was only applied to a salaried 40-hour-per-week job; Mon is 6h, Tue is 10h, etc. If you've got the right gig that can support something like this (many remote SE roles can). It averages out to the same (sometimes more) hours per week, you can plan for more fluidity (e.g. i'm going out drinking with friends thursday evening, so lets front-load some hell days early in the week so we get a heaven day friday), and it tends to really vibe well with engineering workloads (hell days are great for deep focus, centralize as many meetings as possible on heaven days, whatever works for you, etc).<p>And sure, I'm being a little vague in how to attain this for yourself, if its something you'd even want; the sin of Insight Porn. It really comes down to "find a job that allows you to do it", and boom, Luck has entered the chat (with some mitigating "Skill" in being in a desirable field, knowing the right questions to ask in an interview, etc).<p>All that considered, I still like the advice. If I want to spend my free time with loved ones; its so much more valuable & meaningful, to me, to spend an entire afternoon and evening every other day, or even only once/twice a week, than just an evening some/most evenings. Everything is better without interruption; work & play; and classifying your days as "WORK/play" versus "PLAY/work" rather than trying to evenly split every day, has just been better for me. YMMV.*<p>Of course; extending this idea to "3 work days per day, that's 15 work days per week" or "6 hours of sleep per night" is crazy and no one should live like that.
