I grew up and went to a extremely wealthy high school everyone including myself was veryyy well off in my group of friends. 3 billionares in my high school grade.
Anyways we just used all our parents money for awsome shit. Weed, alcahol, had great parties.
We all had cars and didn't pay for gas so we did whatever we want always went out to dinner.
Make a solid group of bros to chill with in your highschool.
Also crush the grades in school probably the most important thing.
But if you claim to be from a wealthy high school use the money to your advantage do awsome shit all the time. When i went to college people were amazed at the stuff we did, even though i thought it was normal. Played paintball all the time back ni the day. Went skiing every weekend at friends houses....just do awsome shit
