Back in grade 9 I had trouble showing my work in math because I did it all in my head. My teacher, not believing that was possible, challenged me one day after class to do a tough problem in my head, in front of her. Upon writing a number down, before I could double check myself, she started yelling at me for being a cheat and a fraud… because I “forgot the negative sign.” That was the day that I stopped caring entirely whether or not others gave me validation, because it’s really more about whether or not they like you rather than whether or not you’re actually right about anything. It’s a decision that perhaps made my life harder for a while, but has resulted in the development of talents which I am quite grateful for, and eventually a near perfect score when I re-did grade 12 math later on to get into STEM.
Seeking validation from others can just as easily steer you wrong, as they are anything but an impartial indication of whether or not you’re doing things right. If the person doesn’t like you, there’s nothing at all in the world which will be good enough for them, and if they do like you, they’ll gloss over and sugar coat everything to the point you can’t even tell if they’re being honest with you.
A lot of people take exception to “art” as an industry though.
