I wish for nothing. My parents were wonderful...I could say I wish the whole Catholic church thing wasn't part of my life....and yet, my rejection of it IS part of who I am, and I like who I am, and so does (did) my parents. (Dad is deceased, Mom is close).
As far as BEING a good parent, I have a lot to say, but the bottom line is, if you are asking and wondering about it, chances are you are pretty good already....seriously.
I think parenting is pretty much the same as being a good person/and being loving in any relationship. First of all, get healthy yourself. Love yourself. Accept and embrance who you are with all your warts and scars.
LIVE well, so your children will know how to.
Listen more and talk less, suspending judgmental "listening", and putting the decision making responsibility on the children whenever appropriate, thus giving them a voice. Ok, some things are up to the adult, obviously, but it never ceases to amaze me how powerful a child can feel if simply given a choice....and that choice is supported....like peas or carrots for dinner.
I used to do this with my kids when they were young, and their N dad (my ex) would call me "Monty Hall ...as in "Let's make a deal". However, now my teenagers have no voice with him at all, and I still help them see their options and make choices where they can, thus telling them they have power over their lives....and their opinion matters more than mine on MOST things. (but because they see my choices, it's not a surprise that we share similar values......). This is not to say they have carte blanche while they are dependent upon me for guidance. I just think many parents take power from their children in small ways each day without knowing it.
DEMONSTRATE and model the life attitudes you value, because if you don't walk the talk, you are modeling dishonesty. Everyone learns more from examples than anything else. Act from loving intention always, and when you act out of fear instead of love (IMO that is when we make poor choices)...own up to it. I know as a teacher, kids respect an adult who admits to fallibility much more than someone who is all together. No one wants a superhero for a parent.
And if you do screw up: don't belabor it: the kids are not your peers OR your therapist. They are students of life, and you are their main teacher. Kids are also resilient, unless you train them to be victims. If kids see us "move through" our trials....they will know it's possible for them too.
BUT the most important part IS: have FUN. JOY is a manifestation of love.....FIND it in yourself, in life, in your kids....
This is what makes it easy for me to find joy....my parents were really good at finding it and pointing it out. A gratefulness of spirit in both of them...lifted all of us up.
