Growing up, I had a natural affinity to music. Throw any musical instrument at me. I’ll learn it in 5 minutes enough to play a simple song.
My sister could draw what she saw.
But she couldn’t do music like I did music and I could not do art how she did art.
So maybe having a few wired traits counted against perseverance for things outside of the realm of those traits? who knows. I don’t believe in forced grit though; chosen is different though.
