During the long sleepless years, I can confirm: each hour wasted not sleeping would become at least two hours of sleepy state during the following day. And that’s not the only ‘benefit’.
Right now is 1 am, and I’m not asleep, again. To calm down, I worked for a while and it looks like this time of the night is so easy to spend extra hours working, easily. But that’s the illusion of a productive state. So I tried to force myself to go to bed instead.
My argumentation is simple: each hour now equals two wasted hours the following day. My assumption is, after the midnight the multiplier is 3x or even 4x, so each hour now is 3 to 4 hours during the day. It’s very expensive, actually.
I guess multipliers can be measured and tracked, as I have assumption they increase each minute after, say, 8 PM. So the situation gets critical at 10 PM, and irreversible at midnight.
I’m trying to avoid blaming myself, but refer to the logic. Even if you think you can do much for this one hour of work, you swap it for 3 to 4 hours of relatively productive work tomorrow. Which is just too expensive. Sometimes, it’s still too appealing to work further, but most times the best strategy would be closing the laptop and getting your night’s rest, to get ready for tomorrow.
