“Feynman Was My Father [On IQ]”, Carl Feynman2024-02-17 ()⁠:

Feynman was my [Carl Feynman] father.

Once when I was in about second grade I said something like “The other kids in my class are like me except I’m smarter than them.” He sharply retorted “Don’t ever talk like that.”

The lesson I took from that is that I could think it but not say it.
