I haven't had kids yet, but I think having them is the most important thing I can do with my life. I can't fix society's problems. I can't even be sure I helped a nonzero amount even if I exerted myself to exhaustion for my entire time on Earth. What I can do is raise someone who is exposed to my principles and ideals. I can carry my meme on so that they may exert themselves for a lifetime that yields an infentesimal result. It's the only way we'll ever make it.
