3. Wait before responding to other people. One of the main characteristics of a know-it-all is impulsivity. Working on your impulsivity directly can help you with your impulse to correct others.. Unless you're a submissive type who likes to be punished for making mistakes, chances are you're not fond of being corrected. In fact, most people like to be right about important things they do, whether it's the best way to cook a dish or repair something that's broken.
People consider me abrasive or aggressive or often just think I'm an asshole because I feel this deep need to correct people when they are wrong.. We all make mistakes in life and we keep correcting them when we realise that that was our mistake. But when someone else points our mistake we feel bad and offended about this correction.
