Many people define themselves based on their job & tbh its what they learn from the Society, I remember steve jobs once said in a video i watched that Everything you see is created by someone who is just a human like you, and many people just don't wanna create their own bcs they are too comfortable being in someone else's creation , I'm not talking about Mother nature, I'm talking about tech and stuff like these jobs , which a human has created, so many people needs to come out this thinking and they can casually define themselves based on their interests and even goals.
