It's ok if you don't feel called to be a mother. I respect more people who know they are not passionate to sacrifice for a child than people who have children 'cause it's no big deal and raise them unloved or worse, in abuse and lack of basics.

When you FEEL the calling to have a child, the inconveniences you mention are just details. You care for yourself to the best of your ability, but you have the child.

So.. yeah. Not all humans procreate and that's fine. Somehow, maybe it isn't proven scientifically yet, but nature "regulates" the balance in the natural and obviously more of us are not adding to bliss, on the contrary.
