As a child, I could recite 'The Rime of the Ancient Mariner'
https://www.poetryfoundation.org/poems/43997/the-rime-of-the-ancient-mariner-text-of-1834, happily that memory is now lost to time.
It was weird circumstances, I'd played the lead in the school production of 'Lieutenant Cockatoo' which was very loosely based on the poem.
After the play was done, I followed up by learning the poem.
Both of those things probably served me well for learning lines for other performances.
But I'm really glad that it's not all stuck in my head.
(One of Rosencrantz's speeches was stuck in there for about 20 years, the one that started with:
"The single and peculiar life is bound, with the strength and armour of the mind, to keep itself free from 'noyance, but much more that soul upon whose life, depends and rests the lives of many..."
(Now I'm annoyed that, that part is still in there taking up room.)
