I don’t think I’ve ever made a good decision when I’m exhausted and it’s late at night.
Fatigue clouds judgment.
Fatigue causes hormones and brain neurotransmitters to fluctuate out of optimal ranges. This in turn causes a cascade of consequences, including excessive pessimism, imbalanced thinking, and lack of clarity.
So if you're up late thinking about a difficult decision, sometimes it's more useful to just go to bed early and get some sleep.
If you have a major life decision to make, get some rest. Make the decision in the morning.
Sometimes the useful things in life are short and sweet. This is one of them.
