Fair enough (and I don't see why you got flagged, as you contribute to the discussion; I upvoted all your comments, I hope ot helps)

Others could be as productive as me in 8h or 6h or even less for all I know. I just have not met such people. Most people I know sleep little and are by my own standards not productive (I mean I would never hire them, sorry if it is rude)

Your other point also makes a lots of sense: I may be losing 2h per day due to sleep. OTOH, I generally wake up by 11am, am done with breakfast and shower by 1 or 2pm, and start working for real by 4pm, so I'm already wasting time by myself :-)

But in a few hours of highly productive work, I often achieve my goals. When I don't, I very quickly find another way to get the results, because IT NEEDS TO WORK NOW!

Lazyness, impatience and hubris are my best qualities!

I think the point the poster was making is that it's possible the issue is with the quality of your sleep. Someone getting a lower quality of sleep will need more hours of total sleep every day to be as well-rested as someone with a higher quality but fewer hours of sleep.

Of course, that's not necessarily the case. Everyone has a different genetic need for and predisposition to sleep.
