Consider the source.
When you get information, look at where or who it’s coming from. Do you trust them? Are they an expert?
When someone criticizes you. Do they know why they’re talking about and are they taking chances themselves. Pay no attention to hecklers.
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.
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?”
Screw “achievement.” Do things you enjoy, share experiences that expand your capacity for joy and compassion. It doesn’t matter if you’re any good, it just matters that you’re in your groove.
You never know what people are going through. Depression, PTSD, anxiety could look like avoidance, anger, risk-taking, promiscuity, etc. Look out for friends, coworkers and loved ones who may be in pain. You don’t need to solve their problem, just allow for the possibility that they’re going through something. Try to give them the benefit of the doubt and not write off “bad” behavior as a character flaw. Offer a non-judgmental ear.
Having an opinion is not the same thing as having an informed opinion.
If you don't know enough about a subject to speak intelligently about it, keep quiet and educate yourself.
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.
In marriage there will be times or occasions when one of you will be “pilot” and the other “copilot” (depending on skills, abilities, circumstances, etc.)
Both pilot and copilot are good! But never be a “passenger” in a relationship.
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.
Toddlers fall... a lot. Most falls are harmless but sometimes bad accidents happen. Head injuries are scary because they bleed and swell. If bleeding doesn't stop within a few minutes or you can see it's a big gash, head to the urgent care. And remember if the swelling goes out (“goose egg”) that’s a good thing: Better out than in.
