Things you learned by yourself that school didn’t teach ?

When you complete high school, it’s like you’re basically on your own. You have choices to go college, get full time job or do nothing I guess but eventually everybody has to work on life. Gotta pay taxes, bills, save money. Is just so much to it. Like when you open up your first bank account. There is so many things to learn like building credit. Protecting your documents. Using credit card and debit cards. Learning to do basic car and home maintance repairs.
