You should write, you are quite talented.
As to the biological clock, I have long told people that my biological clock is digital, so I don't hear it ticking. So many people told me, when I was younger, that I'd regret not having kids. I didn't think the possibility of future regret to be sufficient reason for me to make a step I wasn't sure I wanted. I think sometimes what a neat kid I would have had. I've had many people tell me what a great mom I would be, after watching me with their kids or my nieces and nephews. But I'm not sure I have what it takes to survive the constant worry that doesn't end even once your child has grown. Maybe I never felt in my own heart that I was good enough, that I could give that kind of intense consuming love without driving myself or them crazy, maybe I never believed I was worthy of the unconditional love of a child. Like the unconditional love of my parents and brothers, I might carry a guilt for not seeing what the hell anyone could find to care about in me.
Or, maybe I'm just lazy.
