When we overthink, it often prevents us from taking actions.
It’s not always a bad thing. For example, if you want to stop an impulsive purchase, force yourself to write down all options for the item you want to buy. Once you start listing them, you would think, “Well, it might not be the right time to buy this stuff. Let’s stop working on this boring task and do something else.”
That is one of the weird ways how our brain works. Too much thinking and planning often take away your brain power to take actions.
So don’t think too much when you want to do something good for you. Figure out one action, and do it impulsively. Keep focusing on the most important thing without overthinking. Then you’ll gain momentum very quickly.
