Teach them to clean the bathroom. Wipe down surfaces, clean mirrors, etc. It’s their job to keep it tidy. Everybody pitches in to keep up with housework.
Being well-read is better (and cheaper) than an advanced degree, especially for broader education. Stay curious and read!! Fiction, non-fiction, biographies ...
Have fun at parties! Mingle, dance, participate in the good energy. But if there’s drinking to excess, someone needs to be lifeguard. Young people don’t know how dangerous alcohol can be. And sadly, someone needs to be bodyguard. Men often try to take advantage of intoxicated women.
Start “home economics” school with them. Laundry, cleaning, cooking, how to change a diaper, comfort a baby, soothe a toddler, what's involved in caring for pets, budgeting for food, keeping track of maintenance schedules for humans, pets, cars and machines. Engage with guests, be a good host, etc. Know when and how to tell someone to GTFO of the house (racist or misogynistic speech, etc.) Every kid needs to learn the art and science of home management. Look for and point out examples in books and movies of good home science skills.
Remember what a teenaged sh*t you were before throwing in the towel on the next generation. We’re all self-centered, entitled and oblivious when we’re young. The goal is that they don’t *stay* that way. Be the parent they need, and they’ll listen. It may take a year or twenty, but they’ll see the light if you just pour love into them.
If a girl is drunk she cannot consent. Don’t even think about hooking up when your partner is intoxicated. It’s immoral and illegal. No excuses. No exceptions. . Break this law and you will be (rightfully) charged with rape and you will get sent to prison.
Avoid commenting on the number of children someone has (or doesn’t have.) Its none of your business to ask why a couple doesn’t have kids or remark if they announce they’re pregnant with their 7th (other than to say “Congratulations.”)
Control isn’t safety. Safety is putting in the physical/mental/intellectual/emotional/spiritual work so you’re confident in your ability to address whatever comes your way and thrive, bounce back after getting knocked down.
Work on developing a “no shortcuts” mode. Looking for a faster/easier/bare-minimum option isn’t always bad. People get paid a lot of money for creating efficacy. But there are times when that approach is wrong. Anything you want to grow from (relationships, school, work, wealth, health, knowledge, etc.) those things deserve your full effort, focus and dedication. Play. Definitely play! But don’t f*ck around.
When you meet someone for the first time try to clear your mind of any assumptions about physical appearance. Race, gender, age, handicap/disability, etc.
