@Brick ; not having a crack, but you've told some tales of your past playing up etc. Has Fatherhood made you a "better person" you think, more responsible?
That's a plus in my opinion. Having kids makes you reach your potential more, you can't fuck around as much.
For now I need to teach my son to stop telling everyone he's the smartest so he doesn't come home with black eyes for the next 11 years (including from his sister).
The need to provide for a family makes you work harder and there is a commensurate increase in net wealth.
Motivation to succeed increases. I have realised that my life is not mine alone and with others depending on me this makes all of life's battles an exercise in mortal combat. It's imprinted in our genes. Our ancestors had to fight to keep their families safe and kill more animals to feed them. How you feel about it is no longer relevant.
Who has the strongest will to survive - a man with nothing to lose or a man with much lose?
None of that is a legitimate reason to have kids.
I don't want to work harder to provide for kids I don't really want.
I happy not having kids to worry about.
Doesn't have to be legitimate. It's just the normal thing to do and a driving force in the development of human civilisation as without procreation there is no civilisation.
There are many benefits.
A lot of the responses I get from people when I say that I don't want kids seem like they are shitty with their decision to have kids and want to make sure that you go down the same path as them.
From a Darwinian perspective, I would encourage you not to have children so that my superior genetic features can be perpetuated onto society without the added competition.
Double income no kids = much easier to setup for early retirement also.
