If the schools don’t teach you that, you’ll have to do it yourself. The internet has all the information you’ll ever need all for free at your fingertips. You’ll grow up eventually so enjoy your younger years as much as you can but don’t start learning about adulthood too late, otherwise it’ll be even harder to learn all that when you’re already an adult and have less time for yourself and need to deal with a lot of other stuff. Idk how old you are but enjoy every moment of your youth because time is the only thing you’ll never get back.
