I think you’re conflating the concept of an opportunity cost with a sacrifice. There is a lot of joy in parenting, and not getting to hang out with friends because you have to take care of your child isn’t a sacrifice, it’s the cost of having a child. Not every single thing you give up is a sacrifice.
Nah, sacrifice in regards to your children is absolutely a mindset thing. You can cognitively restructure your thinking in this case.
If you look at your children and think “wow, I’m not getting anything out of this” I can promise you that your children feel this and will become very distant to you when they grow older. They know when you just think they’re a burden.
