These are all excellent and very important values to teach children, but you have to remember that it's not enough to just start teaching them in toddlerhood and lighten up in later years. You have to keep it up throughout childhood adolescence.
My mother did a terrible disservice to me. She never taught me manners or courtesy at home. In fact, she was pretty rude and demanding with me unless we had guests, which wasn't often. Then if she ran into someone she knew when we were out in public, I'd tune out while they were yapping (I'm hearing impaired and have inattentive-type ADD) and when she would finally introduce the person to me, she would embarrass me by saying my name angrily when I didn't respond. It came to where I would wander away when she ran into people because from my perspective, running into someone she knew meant I was in trouble and I didn't know why. Sadly, I didn't teach my daughters manners either because I didn't know any better, but thankfully, a family friend intervened and they grew up well-mannered in spite of my mother and me.
My second-eldest, who inherited my ADD, benefitted the most from my friend's intervention and so has her son. Now, I make sure to to reinforce those manners with all my grandchildren because, as someone with ADD (where social skills can suffer and are vitally important to teach and reinforce), I learned the hard way how important they are.
In a world where manners and respect are becoming lost values and children are using profanity with impunity, I feel it's crucial more than ever before to teach our children all of these things to give them a real advantage in life. And yes, setting the example is vitally important. You won't get these things from your children if you don't give them to your children. I didn't get these things from my mother and when I learned the word "hypocrite" and what it meant, she was the first person I thought of. Don't be that kind of mother. Be the kind your children will always look up to.
Admit it when you're wrong and apologize. Be an approachable and askable parent and if you don't have the answers, get them. Better they get the right ones from you than the wrong ones from the wrong source because they're afraid to ask you. You would be surprised how afraid kids are to ask their parents about things you would rather they they ask you, especially when it comes to sex (it gets easier to talk about that with your kids, believe me--if you don't, they will experiment).
And the most important lesson I've learned as a parent when it comes to honesty, humility, and responsibility: don't be afraid to admit to your past mistakes. After all, we're only human, we all make them, and we make them to learn from. Your kids will admire you more for being honest about what you did wrong as a teenager and what you learned from it than they will if you pretend you were perfect and they find out later (and they always do) that you lied to them by maintaining that pretense. If you do the latter, it will keep them from trusting you in the future and everything you've taught them in the past about values, fill them with shame about their own mistakes, and lead them to fear your judgment if they're honest with you about those mistakes so they won't turn to you for support when they need it most. Better to be honest with them about your past to begin with so they know they can turn to you and that you're the last person in the world who will judge them because you've been in their shoes. They're your children and they will love you unconditionally no matter what you did decades ago (as long as your actions always prove you feel the same about them beyond what your words can). Make sure they know that you're the kind of parent who isn't so filled with "god-like perfection" that you will do the same for them when they need it most.
If you mess up, it's never too late to admit it, apologize, and start doing things better, even if it takes time to get it right. Just ask them for help and tell them it may take time to change old habits because it does. Your kids will understand that if you are understanding with them too. Discipline of course, but also recognize sincere efforts at improvement.
Those are all good values to teach out kids, most importantly, we as parents should live those values and practice them through our daily life. Kids watch and learn by what we do , not what we preach....
Unfortunately so many patents today don't believe in properly disciplining their children, so many of them are just so out if control. Kids need to learn all of these things!
I also think parents should teach they're children acceptance. My mother has taught me to be accepting of other races, religions, etc. However, my father is somewhat prejudice against certain religions no matter the person. I've had to block that part out to learn tolerance and acceptance of all people.
