Here are the 2 worst habits of overthinkers. Number one, they spend too much time complaining. They look for grievances, they look for things going wrong, and they gripe about them. So here's the antidote. The 24-hour no complaining rule. For a full day, 24 full hours, don't make a single complaint. Notice how much better you feel. Second, overthinkers spend too much time imagining worst-case scenarios. When you rehearse worst-case scenarios, you end up in some sense living them vicariously. That doesn't make you feel better. It makes you feel worse. So stop doing these 2 things and your overthinking will begin to decline.
