“I don’t learn this in school :(“
Hey here’s a question what steps have you taken to increase your education and knowledge since graduating?
12 years is not nearly enough time to teach you everything to know about the world, especially when the starting point is “a says ah” and “1+1=2” and “rain comes from clouds.”
There are people who spend their whole lives in pursuit of knowledge and do not run out of stuff to learn. If you want to be well-informed and knowledgeable as an adult you have to actually make your continued education a priority. The library is free, thousands on online resources are accessible to all, and somewhere near you is an affordable museum or culture center or zoo or art display that can give you information you didn’t know.
