Well mine are not all grown up yet, or successful, etc. But they have survived so far, and one has flown the coop and got a job and a cat, with two more on their way through university.
I always tried to praise effort and not results and praised specific things, never a blanket job.
I tried very hard to make them treat family as if they respected them (and to fake it if they didn't) and above all not to touch other people's things, including mine, as lack of respect for personal property expresses and leads to all sorts of problems. Making them observe this rule was important to me and I think it showed them that other family members have rights. Plus I never lost any jewellery or makeup, and got to spend time by myself in the loo.
For my part I apologised if I had been ott or unreasonable or unfair with them. At the same time, if I said 'No' then I never changed my mind , if they were being annoying I told them, and if I asked them to stop doing something I did not let them continue, even if it meant leaving a cinema because someone was kicking the back of a seat, etc.
We always chatted a lot and still do, and I try to share my interests with them and appreciate theirs. I don't criticise their taste in anything which means I listen to Taylor Swift on long car trips grrr
*Sense of humour as much as possible (though nobody is a saint and there are no medals for martyrdom).
*Pick your battles.
*Allow choices among reasonable options and those respect choices, when they are small. Discuss finances with them as they grow to be tweens, without burdening them with your money woes, but they have to start understanding money at some point and early is better than late imo.
*Avoid empty threats. Keep it realistic and say what you mean.
*Make them get part time jobs when they are old enough.
*Make them help with the family meal and teach them to take care of themselves -- laundry, cleaning up after themselves, responsibility for their own homework/excuses to teachers.
*Make sure they know boundaries and expectations that are clear, and start this at a young age.
*Don't talk disparagingly or enviously about other people behind their backs with your children. 'Comparison is the thief of joy'.
*Have a 'no questions asked' policy for when they are at a party and want to come home.
*Share gestures of affection long after they are small children. Don't keep score, don't sulk. Be kind when you have a chance to.
*Don't try to compensate for time with stuff. Time together doesn't have to cost much.
This may be controversial, but save any crying you need to do until you are out of earshot of your children except in cases of family or pets' deaths. Don't put your children in the position of ministering to you.
Also maybe controversial, a 'mental health day' or two off school can be a great and good thing.
YYY to no labelling, pigeonholing.
Also, let them develop strong friendships and become friends with the families of their friends. Welcome their friends to your home, be it ever so humble. I am a single mother who will be forever grateful to the lovely men, the fathers and grandfathers of DS's friends, who have showed him their versions of what a father should be and what family life can be, and to the fathers and grandfathers of the DDs' friends too.
I agree with being positive, practical, on top of things and not seeming to panic.
