There's an entire pack of things you can do to learn things however be certain not to pick some unacceptable one. You can go to class and educators will show you things\subjects. You can ask your folks and they will show you right/wrong. Try not to ask outsiders! Since the state may not be valid. For example, they may state "smoking may be cool!" when it's truly not. You can get Cancer, Heart Attack so ask who you TRUST, not some more abnormal
