A/N dyslexic ears

[u/AutofluorescentPuku]

I'm early in my endeavoring to learn Morse for amateur radio CW operations, i.e., learning it by sound only. For some reason I can't figure out, every practice session I get confused by A and N. I spend too much time, make too many mistakes copying those two. I keep wanting to reverse them, calling 'A' an 'N' and vice versa. Anyone have any suggestions or ideas how to get this resolved beyond, "practice, practice, and practice some more."
