When you tell people that children aren't for you, they feel you're threatening society as a whole. It's not easy for them to see it as just a personal choice. A childless life is seen as incomplete and unfulfilled. However, it is entirely possible for a childless woman to live as fulfilled a life as any mother. There are as many definitions and degrees of fulfillment as there are women, but very simply speaking, if you are satisfied with your life and have achieved happiness, then you are fulfilled.
Some childless women find gratification in a strong marriage.
For others, this fullness of life is born of time and energy to pursue personal enthusiasms, achieve career goals or work within the larger family of community. Whatever the means, fulfillment comes with realizing our own human potential. But fulfillment doesn't necessarily mean a life that's full. Their constant frustration and weariness make me wonder. Though my daily schedule is radically different from any mother I know, the rest of my life isn't.
