I’m not sure there is a clear correlation, Einstein, Aristotle, Descartes, Shakespeare, Napoleon, Galileo, Jung, Socrates, Wagner, Tolstoy, Dostoevsky, Jobs, Picasso, Tolkien, Darwin, Planck, Bach, Marcus Aurelius all had children.

That's comforting to know. Amongst the more crazy femnistis they're talking about how woman that don't get children live longer, are healthier and probably "happier". You probably can be very happy without having children. But you gotta find something that you love, recognize it and start focusing on it. Having children might be one of the best ways to love in life - but, there are many ways. Also: Being a high achiever doesn't mean that you had a feeling of fullfillment in your life.
