So happy to hear you are loving your Yamaha Pacifica, and learning to play 'Wish You Were Here'. Fun!
I started when I was a pre-teen, and I think the first song I was able to play through and feel like "I can actually play guitar" was "Leavin' On Jet Plane." My Dad had the vinyl album and played it a lot, so the song was kind of embedded in my head!
Knowing the song really well is super helpful in learning to play it - and ups the joy factor too, I believe. It sounds like you have a good thing going with "Wish You Were Here', especially the parts that never get old!
Have fun - Lisa
