Making Better Decisions
I can trace all my problems back to a decision I made while tired and unfocused. This is exactly what former-President Clinton talked about before.
“In my long political career, most of the mistakes I made, I made when I was too tired, because I tried too hard and worked too hard,” he told Rao. “You make better decisions when you're not too tired. So that would be my only advice.”[1]
That isn't a call not too forgo sleep once in a while to work hard. It means you should be rested when making important decisions. Unfortunately, you make important decisions in your life every day. I have no solution to that. I will say, though, that this applies all the way, to my relationships when I've going through rough times, to the ebay seller I said I would buy from. Before you pull a trigger, catch some shut-eye.
At the very least, it'll save you a bullet.
