Do you have a litany that helps you when you feel tired? I find that when my lizard brain wants sleep it is hard to continue work, if you have any solutions that work for you I'd be happy to let you other-optimize.
No, sorry. Part of my current system involves optimising strongly for sleep, so feeling tired usually means I should stop working. If it's something I absolutely need to get done then it's usually urgent enough not to need the extra motivation, or I guess how long it will take and then set multiple alarms on multiple devices for early the next morning, allowing an extra half hour to an hour to crawl out of bed and wake up that early. (I find it easier to convince myself to get out of bed stupidly early than to pull an all-nighter)
On the other hand, if you ...
You should probably read the Anti-Akrasia Tactics Review, if you haven't already. There's lots of useful stuff there, and if it works for you but you haven't read it...
You should totally go read it, implement it, and not come back to this thread until you've internalized your favorite tricks.
Feel free to discuss outcomes here.
Did anything work for you?
Is there anything that should be added?
Note: this is basically a "bump", but I suspect that it's a worthwhile reminder. Downvote me if I'm wrong.
P.S. I'd actually really enjoy feedback on this.
