I’m a pretty even-keeled person. A friend recently asked how I’m able to stay so calm in most situations. Part of it is my personality and upbringing. But also, I’ve learned to quickly filter out things others may choose to worry about—specifically, things outside my control.

When I encounter something that could be worrisome, I ask myself, “Is this within my control?” If the answer is no, I simply don’t worry about it. It doesn’t make sense to waste my mental real estate or time on something I have zero control over. I can’t influence the outcome, so I shouldn’t worry about it. That doesn’t mean that I’m not aware of it or that I ignore it. I take note of the situation, but I don’t go further than that.

Not worrying about things I can’t control is a helpful mental trick that’s allowed me to allocate more mental bandwidth to what matters most: things I can control.
