Feeling no particular drive for having children for most of my adult life, that changed when me and my partner got the very shocking news that she was pregnant last november. We were there to start the process to harvest her eggs, as she was about to undergo aggressive cancer treatment that would leave her unable to conceive children afterwards.
The pregnancy turned out to not be viable, and two weeks later the treatment started.
Seeing that heartbeat changed everything. Nothing seems to matter anymore in comparison to having kids, as a life goal.
