Sitting around in your comfort zone, doing the same crap over and over, and jerking yourself off until the day you die is an empty, dull life. A more valuable life is more about stuff like pushing yourself to try new things and create positive experiences. The more of that you do, the more value your life has. And if you’re seeking out positive, new experiences to create, why wouldn’t raising kids be near the top of the list in importance? You’ve always heard about what a rewarding, life changing experience it is, after all. Why wouldn't you want to give it a go?
I think anyone who is happy to play video games without doing much else every day for the next twenty years and claims that their life couldn't be any more valuable is just wrong.
