When I was ten I read Heinlein's Red Planet.
When I was eleven I read Heinlein's Puppet Master and I was hooked on Heinlein but not forever. I read most of his SciFi short stories that stretched way back to the late thirties. Most were excellent, some were so-so and some were bad.

Then later, after I figured out that I was a man equal in judgement to all men, I read "Stranger in a Strange Land".

The book was interesting but disappointing.
And so to my great disappointment and pleasure, I found out that I knew more about life than Heinlein and have remained so since.
