Bias.
or why you shouldn’t think to know best. Do you enjoy doing certain things, knowing you are not a professional at it? Singing? Cooking? Playing an instrument? Writing? In all matters, you should know the borders of your ‘talents’. Know at what points to stop, and always be modest about it - knowing your strengths is great, but it’s even better to know what strengths you shouldn’t overemphasize. That way I for example have tried living these past years, always trying to improve, but loving the moment of me trying to accomplish something which I thought I wouldn’t be able to accomplish. You might also have one person in your circle of friends who systematically has to prove that he, in opposition to you, has studied, learned or in any other way had a beneficial exposition of knowledge, practice or w/e concerning your loved activity. Should you dare to try to expose one of them to a person like that, beware: a tornado of multiple captain obvious’ is approaching. Even non-self-centered people show this phenomenon of trying to correct, ridicule or look down on you. How should one ever deal with this? It plainly ruins a day sometimes. A sentence to you, my dear: You should understand that going through life contains the necessity of not everyone being best at everything, but going through life as friends should contain love and acceptance for the other person. Sometimes, let that shine through. Show your appreciation, and feel happy to see someone else trying at something you might be best at. Grant them that much air to breathe. Our society is competition-based enough for my part of the cake already, please don’t let that come into my concept of friendship and trust.
