I think an underrated way to improve your life is just to make sure the various things you do anyway are aligned in a harmonious way.
I know that sounds “woo-y,” but here’s what I mean. There was a study done a long time ago evaluating parole hearings. Criminals who had served a long sentence, but were eligible for early parole. Thousands of such cases were catalogued and evaluated to look for patterns in whether or not they were approved or denied (a monumentally important decision). The most important factor turned out not to be severity of the crime, length of sentence served, good/bad behavior, etc. It also wasn’t race or anything like that.
It was whether the judge had eaten lunch yet.
Turns out the cases heard right before lunch, when the judge was hungriest, had a far higher rejection rate than the ones heard right after lunch, when the judge was sated.
So what I’m saying is, scheduling the important things in our lives to be in harmony with our natural patterns of eating, sleeping, etc., can have a major impact on how smoothly everything goes for us.
Have a snack, take a nap.
