We tend to worry. A lot. And while some of it’s legitimate, justifiable concern, most is simply unnecessary stress we’re putting on ourselves. I like to break down the umbrella term that is “worry” into two categories: things we can control, and those we have no control over. If your problem falls into the first one, then yeah, you can worry, but try not to worry too much; it’s far more beneficial to take action to solve the problem then to wish it away. And it if falls into the second one, then why worry? If you have no control over it, then you might as well learn to live with it.
