Vocabulary.com explains: The noun mediocrity means the quality of being average or ordinary. Mediocrity has Latin parts that together literally mean "halfway up the mountain."
If you measure your life by looking at and comparing yourself with others you become average and ordinary. You perceive them as being better and more successful than yourself. This causes feelings of inadequacy, and makes you believe that “the grass is always greener on the other side”. You get frightened of living your own way and this causes your path to become clouded and your vision to be blurred. Fear of the unknown sets in.
No single person is average or ordinary. We are all unique beings, every one of us is one of a kind. That makes us anything but ordinary. We are so good at putting ourselves down and finding faults. Instead we should look at everything we can do that makes us different and celebrate this fact. Look at your life, embrace the challenges and with every step you are forming yourself as the most unique, different, and excellent person that you are. Go out into the unknown, knowing that you are enough, know enough and have enough to live your very special life. Only you can live your life!
