My brother once told me a story about someone whose parents pressured him a lot. I don’t remember who it was with exactly – it might have been R’ Shlomo Zalman zt”l.
This boy’s parents wanted him to be the next gadol. They pressured him to learn all day. No time for playing – only for learning. R’ Shlomo Zalman heard about it and was against it.
Sure enough, when the boy got older, he resented his parents for it, and went completely off the derech. When R’ Shlomo Zalman heard this, he said, “Kids need to play. If they doesn’t play when they’re young, they’ll play later.”
