If you are strong and capable you should have kids to help build a better tomorrow. There aren't many young women who want to have kids because there aren't many young men who seem strong enough to bear the responsibility.
I always enjoy when the decision against having kids is subtly framed as a weakness or a character flaw.
I posit a different guideline: If having kids is something you feel is of vital importance to you personally and not because other people expect it from you, then by all means, try to find someone who feels the same way and have kids.
