I'm curious whether this would hold for creative, mentally taxing work like programming. I'd love to get 2.5x the coding time in, and I've found that I can often ignore my limits and keep coding long after my brain tells me that I'm exhausted...but then when I wake up in the morning, I find that I really should've stopped when I got tired, because it will take me 2.5x the time to unravel the mess I made the night bef…
It works when it should. As a teenager from a poor family in India, I would generally go on 5 hour sleep- My waking live was spent going to college, studying for long hours in the library and doing late night studies at home.
I used to sleep between 3 AM and 9 AM in the morning.
I didn't even like I was doing anything great at all. It felt more like 'opportunity'. Because frankly my other friends from a similar background where having it way worse, most had quit studies and were doing small time jobs to support their families.
I had these kind of episodes in my life quite a few times. Generally something good comes out of it. And it has always felt like 'opportunity'. Stressful, tiring, taxing and demanding of course, but I feel blessed to be even given the opportunity to undergo the struggle.
