I’m doubting. Simons might be an exception given that he got a PhD in maths at age 23. He was always smart, and I think he was bound to excel in whatever field

I’m doubting. Simons might be an exception given that he got a PhD in maths at age 23. He was always smart, and I think he was bound to excel in whatever field he chose. But people don’t need be extremely smart to get wealthy. Just executing well on a simple idea can make one extremely wealthy, and there’s considerable luck involved. There’s also the need to have persuasive skills, connections, charisma, and all that to convince people to follow their vision, aka Steve Jobs and Elon Musk.
