I gage the amount of farm chores I do daily by my chess playing ability that day.

Usually in the morning I'll play a couple games to see if I'm on point that day. I'll run a couple more before the lunch break and another couple matches before evening. If I make tons of blunders or lose to people with a much lower score than me, I limit my farm work to minimal maintenance, not advancements or long hard days, and spend the extra-time doing my day job.

I find it's a good metric since farming mistakes can be, at worst, life or death or, at best, a waste of several hours in the heat and mistakes at my job are generally insignificant relative to the slow moving bureaucracy of the company I work for.

I wish I had a similar self-awareness metric for my emotional state to gage when it's a "sit outside and observe the animals" + VS "stay inside and shower fiancé with affection" day.
