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.
I once asked my mom if my grandmother (her mother in law) was rich. Her reply: “No, but she likes to think she is.” I think she meant my grandmother spent money like she had plenty of it when she really did not. Can relate. I hope you do better!
Venting is crucial but not always appropriate. Make sure you’re in the right place (no chance whatsoever of being overheard), the right time (take care of business first) and that the person you’re unloading on has the mental bandwidth to listen to you vent your emotions. Avoid interrupting if they’re busy, or not in a good headspace. You’ll know this because you asked.
Speak up when it’s called for: Fight injustice, stand up for others, etc. but shut the F up if you’re thinking about offering an unsolicited opinion or advice about anything you’re not personally an expert in.
Offer gifts to the Lord. Maybe it's your school work, or your career, or the kid you raise, or your life in general. Wrap it up and make it a present to the Lord.
You can’t hit ‘em all outta the park. Some days (dates, reviews, vacations, report cards, etc.) are just going to fall flat. No worries, the next one will be better.
When you feel sad, mad, confused or in any way upset, go to a quiet place to catch your breath. If you can sit with it and let it tell you what it wants to tell you, then you become its friend. But if you try to deny the feeling, or numb it, it grows much stronger and it fights you.
Start a yearly “review” right before school year. Raise allowance as appropriate. If they want more money, they’ll have to take on more responsibilities.
Super good-looking people often don’t develop good people skills because they’ve been able to get by on their looks. Listen! Beauty fades. Get curious about people who don’t necessarily catch your eye right away.
Inevitably you will make mistakes in your career. Someone will dress you down for it. It stings. But they are doing you a favor. Thank them for it. We all have to learn, and we can’t do that if our pride gets in the way. Be humble and accept constructive criticism.
