Yes, I think groundhog day and similar stories ( Mother of Learning, Time Braid) give great examples of this- if you really want to drive this home to your system 1, I recommend the "split selves" and "second chances" techniques in this post to drive it home by imagining that YOU'RE actually in a looping fic.

Note that I don't think that it's necessarily bad to drive home an "Honor Harrington" type message where the hero is practicing a lot at skills they're already naturally gifted at - I think this is the most effective path to success, and you definitely don't want ot hammer in the meme of "even if I'm naturally really really bad at something, I can be the best through practice."
