Think about building a career. Take low-paying or no-paying jobs that will give you the experience you need to build it. It's not all about the paycheck, especially when you're young and don't have too many bills to pay.
Okay algebra and geometry but other than that, spend time practicing addition and subtraction, multiplication and division. That’s 99% of the math you’ll need to know if you’re not going to be an engineer, etc.
Surprise! You’re not perfect. No one is. Do your best, but don’t expect perfection from yourself or any other human, young or old.

Keep porn to a minimum. Never at school or work. It's normal to be curious but it's really not a healthy representation of sex. Porn is a business. It's designed to get you off, not to be realistic or educational. That's not the way sex looks or how you're expected to behave. Try O.school instead.
Read BIOGRAPHIES. So many interesting stories and valuable lessons. Historical figures, those close to them (those are often the real treats!)
Also people from all walks of life, different industries. Artists, entrepreneurs, athletes, statesmen, etc. Bonus points for listening to the audiobook if subject narrates it.
Pretty much everything boils down to looking for love, its many forms. Look in good (creative) places. Avoid looking for love in bad (destructive) places.
Talk about how choices become habits. Habits can become addictions. Describe how pathways are literally dug into the brain and it's very hard to change them once those paths are made.
Grandpa always said everything boils down to how you treat people.
Always treating people with kindness and respect is the most important lesson he wanted to get across to us.
