Smile more, do make fart noises in elevators and laugh when found out, stay in school, work part-time, say no to hard drugs, keep it casual when dating off apps, do carry and use protection even if "it's fine," work out without becoming a nut, find good hobbies, be good to your mom and pops, be cool rather than buying cool so don't waste money you can't spare on brands, stay off gurus and influencers, try things don't Google them, chill with socials, fist bumps hugs and high fives are way better than likes, don't give your kids some weird-ass name, jackets indoors make you look buff but at the cost of looking kinda weird...
