I think self awareness is vital as a parent.
I know that I was a much better parent when my DC slept in their own beds and that co-sleeping would have turned me into a screaming, touched out wreck( different for others I know).
Important (to me)
Routine: it should be warm and loving etc bedtime routine and makes DC feel secure- they like knowing what is coming next.
Add in lots of exciting discoveries, different things to see and do.
Having a few rules that are the bedrock of our family life:
Sleeping in their own beds - they were bed hogs
and slept well from a young age - it was not negotiable.
Books -a world of excitement and discovery awaits, it doesn't matter if they read Classics or The Beano , they will never be bored.
Eating at the table, table manners- a life skill. Again not negotiable.
Everything you do as a parent will inform your DC- if you shout and yell, then don't be surprised if they do it back !
Insist from an early age that they are respectful to you and others, no hitting, rudeness. If your toddler is rude and disrespectful and you do nothing- god help you when you get to the teenage years.
Allow them to have tantrums-its normal, dont jump to stop them -be firm ,consistent and remember they are vital in their development( learning self awareness and control)
Allow them to be bored and have time to just be- no one needs a life completely mapped out for them day to day. They learn who they are and self reliance.
Im sure there are tons of other things but try to enjoy as much as you can!
