My question would be why you value your kids time more than bouldern?
Because you made them? Because they consume so much time with them?
Or because you are just better in being a parent and biological getting satisfaction out of it?
Unfortunately for me I'm not sure if I would end like you or the other poster who regrets it sometimes.
Also I'm not sure if I want to force another/new human through my experiences like going to school etc.
In dune the king new/realized that he can't do what is necessary but has to prepare his son to do so.
I have the opposite though: perhaps I need to not to have kids to stop the cycle of creating meaning through procreation.
Yes I overthink stuff and one way or the other I still think becoming a parent would be a life changing experience but besides all of the normal thoughts climate change comes on top of it.
