People who have high standards fear being mediocre. I thought of that when I read this: Opinion | I’ll Never Be Rachmaninoff – The New York Times.
People without high standards never worry about that. They do stuff, and the result is what it is. It comes with no judgment, for the most part.
Being fearful of being mediocre is twice cursed. First, if you fear that, you likely will not attempt things that could bring you joy and happiness due to your fearfulness. Second, you are already mediocre at some many things already, and yet you turn a blind eye to them, convinced that the few things you excel at removes the label of Mediocre from you. I have rarely met people who are great at one thing not be mediocre at many other things. There’s only so much time, and greatness comes with tradeoffs.
Don’t fear being mediocre. You already are! Go out and enjoy what you can. You may find the things you start off being mediocre in at first are things you end up being good at later. Not that you need to get good!
