While many of us place a lot of worth on external achievement, there are many variables beyond our control that influence the outcome of a situation. Even if we do our best and do everything right, we might still feel “not good enough” because those external variables mean we didn’t get the gold star.
Others have different ideas about what “good enough” means and looks like, but you have no control over that. There will always be someone who is more talented, more accomplished, more X and more Y than you are. The only person it’s helpful for you to compare yourself to is the “you” from yesterday.
