At 18, I had no business even being responsible for a kid for a day. I hope the stability (both mentally and financially) that I'm able to offer my kid in their development years far outweighs the fact I won't be around as long.
Might this not be a consequence of how "we" were raised? In the past there were 18 year olds who were successful and responsible leaders of nations. Marcus Aurelius became emperor at 16! My parent just wanted me to go to college and earn money so I grew up with a rather 1-dimensional and hedonistic perspective on life.
I'll be encouraging my children to have children as early as reasonably possible. In part it's because of greed - I want to see those grandkids, and maybe even remotely possibly great grandkids before I die, but it's also because it's what I wish I had done in hindsight. Having children has not only been the joy and pride of my life, but it also gave my life much more meaning and direction. In any case, I also think it's completely appropriate for grandparents to play a significant role in the raising of children.
