Maybe the problem is managing your expectations. There’s nothing wrong with being a good-enough mom and an employee who doesn’t hate their job. That’s a hell of a lot more than a lot of people have.
My big goal in life? To be content. I don’t have to conquer the world - hell, I don’t WANT to. I don’t want to be CEO of *anything*. I would just like to carve out my tiny little nook of space in this world where I can be myself and be happy. That’s enough.
