Recruit the kids to help with cleaning the house. All hands on deck "round-ups" are fun and efficient: Round up sippy cups, trash, dirty laundry, give-aways, etc. Time them for maximum enthusiasm: "60 second trash round up...Go!" See who can collect the most trash in 60 seconds.
Stay fit. Try to increase fitness every year in some way: Strength, flexibility, endurance, or a specific sport or practice. Never take your body for granted.
Discuss prescription (and OTC) medications. Doctors prescribe or recommend these medicines, they’re not for fun and should be taken seriously.
Discuss how medicines are obtained, never shared, which is dangerous and illegal.

When you have no idea what you’re doing, just be kind. Be brave. Think critically and make the best decisions you can in the moment. If possible, find resources to learn what you need to know. Ask for help if help is available. Do your best and don’t sweat it.

Speaking truth to power is important but should be done carefully. Before you speak remember this: Is there anything self-serving, mean-spirited, or ego-driven? If you’re sure your feedback isn’t tinged with those things, then I’d say you can be comfortable telling it like it is. Note: when you’re young (less than 30) WAIT to be asked before you spill your guts! Always be kind, professional and consider what you want to say carefully.
Put him in charge of figuring the tip out when we’re out at a restaurant. Calculate 15% or 20% etc. Also emphasize that the difference between a good tip and a great tip is usually just a few dollars but it makes a difference to the recipient. Be generous with people who are in service professions.
Teach them about Oliver Cromwell’s rule: “I beseech you, in the bowels of Christ, think it possible that you may be mistaken.”
Leave room for your mind to be changed by new evidence or perspective.
