But deciding not to have children is a very, very hard decision for a woman to make: the atmosphere is worryingly inconducive to saying, "I choose not to," or "it all sounds a bit vile, tbh." We call these women "selfish" The inference of the word "childless" is negative: one of lack, and loss.

The problem with battling yourself is that even if you win, you lose.
