Sleep paralysis runs in the family. If you ever feel like you’re awake but you can’t move - don’t panic. It will pass in a minute. It’s just a lag time in your sleep/wake cycle.
Things are rarely perfect, but things that are less-than-ideal aren't all bad to the same degree. Let's talk about making buckets for "not ideal but I can put up with it" and "deal-breaker." Works for all kinds of situations. Another variation of this is to grade the suckiness of a situation on a scale of 1-10. Have them decide at what point action is needed vs. just putting up with it. This one works well for hunger. Yes, you're hungry, but on a scale of 1-10, how hungry? It also works for relationships! There are plenty of things about a spouse that are less than ideal, but how many are true deal-breakers? Teach them to understand the difference.
Let it go. They’re going to make really stupid choices. I drank AND smoked in high school. We all go through it. They need to be able to trust you and rely on you. They’re navigating the world and they need a safe harbor. Be that safe harbor. It’s more important than fighting over stupid behavior. Let them know you don’t approve - sure, but fighting over stupid stuff is just going to make you both bitter.
When I say I want you to be happy I’m not talking about pleasure and ease. I mean purpose and pride you in yourself, meaningful work, and a solid group of friends and family who loves you for who you are, so you don’t ever have to pretend to be something you’re not.
A useful opening line in a conversation (personal, parenting or professional) is “What should I know about ...”. It shows you understand you have something to learn, and it makes people feel valued. “What should I know about what’s going on at football practice?”
Have dinner guests sign the under side of the dining room table. Let the kids’ friends sign too - or have their own version of a guestbook - the inside of a cabinet or the basement door, etc.
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.
