Celebration and acknowledgment: Make a big deal over little-big things and teach them the same: getting their braces off, or a cast on a broken bone, a friend gets a new car, etc. Always acknowledge the sad that someone is going through or the difficult situation. Applies to all ages.
On marriage: Your spouse will change. You will change. Some for the better, some parts for the worse.
Tastes, plans, health, body shape, education, needs, beliefs... all change throughout our lives. It’s growth. (It’s also decay!)
Support each other through both.
Encourage each other to be true to yourselves. Don’t sweat the small stuff. Be kind. Pray for each other. Have fun together. Keep learning about each other. Be your partner’s biggest fan.
Default to "nice guy." Meaning it should require something significant for you NOT to be nice. Give people the benefit of the doubt. Cut them (and yourself) some slack. Life is hard. We're all in this together.
They’re very teachable at this age. When behavior is bad, send to their room for a brief “time-out.”
Then go get them by sitting and putting him/her on your lap. Talk (1-3 sentences) about why we don’t behave that way and how I expect you to behave instead. Then hugs and kisses.
If the offense is really bad, introduce consequences (which have to be immediate, they wont understand missing out on something hours from now, won’t make the connection.)
Change “I need to” to “this matters because”. Instead of “I need to walk the dog” say “it matters that I walk the dog because he needs exercise and to check p-mail.” (Helps!)
Your spouse will be absolutely unbearable roughly 10% of the time. So will you be, by the way. Give grace. Receive it too. Also, physical distance helps, even for a few hours.
Grandpa was a Marine, though you’d never know it. Slight in build and oh-so gentle natured. But underneath he had a good bit of grit. He never complained. He once told me “You can stand any amount of pain for a little while.” (Basically saying suck it up and hang in there until help arrives.) I’ve never forgotten it.
