Have you ever had one of those lightbulb-comes-on-moments where something from your childhood clicks and makes sense? I remember the moment I understood the saying "sew buttons on your underwear." As a young child, my standard response to anything and everything was always, "so what?" To which I continually received the response "sew buttons on your underwear." No one would explain it, and I wasn't the type to ask. I just accepted and moved on. It wasn't until I was in my teens that I had that lightbulb moment, and understood.
I love those unexpected moments, whether it's remembering where you have seen someone before, solving a longstanding mystery, or something finally making sense. Those are the times we tap into that potential our brain has.
