I don’t think there is a single person out there who wouldn’t want to do something and know they did it perfectly. The thing is we are human and we will never be perfect.
As parents we try our very best to be the best parent we can. We want to raise our kids to one day be adults and be as successful Aa they can be. But no matter how hard we try we will never be perfect at it. We will make mistakes along the way. We will doubt ourselves. We have to learn from both our own mistakes but also from those parents around us so we can be the best parents we can be.
So perfectionism, will we ever obtain it as a parent? No, but we can do the best we can.
