"The goal of any scheduling algorithm is to fulfill a number of criteria:

• no task must be starved of resources - all tasks must get their chance at CPU time;
• if using priorities, a low-priority task must not hold up a high-priority task;
• the scheduler must scale well with a growing number of tasks, ideally being O(1). This has been done, for example, in the Linux kernel."

Translate to life:

• Always leave some time for different things. Don't let any particular aspect take so much time as to not allow you to enjoy other things. Aka the "work-live balance".
• You shouldn't let unimportant things hold up important ones
• Don't overthink so much about optimizing what to do, that you don't end up doing anything. Aka (by me) the Metawork fallacy/trap

The answers to a happy and fulfilling life were lying there in front of me, all this time, lurking in the code behind the screen.
