When something is not right in our lives, we tend to focus only on it. You may take comfort in knowing that our human brains are hard-wired to see negative things more clearly and focus on them more. It’s a throwback to when we were cave dwellers. Failing to notice a saber-toothed tiger lurking in the shadows was a possibly fatal error; failing to notice a rose blooming in the meadow was not. We see things that are wrong in our lives and we obsess about them. But as rational beings, we can also use tools to help us focus on other issues.
