I believe it can be very hereditary. My parents weren’t/aren’t very creative (although, my mom can play guitar and sing a bit). I did not come from a creative household. Yet, from a very young age, I was drawing a lot – I still have drawings from when I was 8 years old and up.
My mom’s side of the family are quite talented in many different creative areas (musicians, artists, photographers and architects). My sister can sing (also great at interior decorating) and my brother can draw cartoons. I can draw pretty much anything, dance, write poetry, photography, woodworking, and play musical instruments (all of these “talents” I learnt on my own and had a natural ability to do so). Lol, I don’t know the notes I’m playing on piano but, somehow, I make music on it.
Most people in my family did not take lessons or classes ..they just sort of did it on their own I guess.
I do believe, though, that it takes both nature and nurture to excel in creativity. Not either or.
