There’s one thing I’ve noticed that makes the difference between an adult and someone who is over 18: That person’s proclivity for reading. Books make you smarter, yes but they also make you kinder, funnier, more empathetic and more tolerant of opposing viewpoints. Travel has a similar effect but is a lot more expensive! If you want to be a genuine grownup, read (or listen to) everything you can get your hands on.
Practice real-life mental math: Calculate time / age: If someone was born in 1994 how old are they today? Make change in your head: Cost is 14.27, how much change do you have if you give the cashier 20 bucks? Calculate percentages: tips, tax brackets, sales!!
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.
Respect people’s boundaries / quirks. Someone who “doesn’t fly” may have fear of enclosed spaces due to anxiety or past trauma. Someone who doesn’t drink may have had a parent who was an abusive alcoholic.
Don’t laugh, question or prod. If they want to talk about it, fine. Otherwise just accept their boundaries.
Remind them there’s nothing they could ever do to lose your love. They’re so afraid of disappointing you. Emphasize the difference between making mistakes and being a “bad” person.
It's very important to me, the idea of the scale of good and bad, of beauty and suffering. I think we should do everything we can to increase the beauty and to take away from the suffering. We have to work hard to tip the scale in the direction of good.
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.
