Curtis McHale has a good thought experiment.
If you had a finite amount of energy to use up and when it was gone you died, what would you not bother with? Would you worry about things you can’t change? Would you drop those clients that are stressing you out?
Would you be doing much of anything that you are doing now?
This idea is very much in my wife’s wheelhouse. She actually has a finite amount of energy to give, yet she “borrows spoons” from months in the future probably every day.
