I think mindset comes from your peers it comes from your parents and but where does success mindset come from specifically I wonder if that does come from dad now in my case it came from my mother so I can't speak to any other situation. My mother was the one who said you go into college from the time I was a fetus told me I'd be successful  from the time I could understand language always did. He spent years and years trying to figure out the formula for success by studying other people's ways looking for patterns, which is how he came up with talent stack idea of combining useful talents.
