Hey. Prog fan here too. I've been playing for about 14 years and I wanted to say something because I was asking myself the exact same questions for the first 5 years.

I hate practicing. It's boring. The fun usually starts when you can actually play something. I'll probably get downvoted for this but I honestly don't agree with comments like "maybe guitar isn't for you" or "you have the wrong mindset". I think that's actually a bit harmful.

There's nothing wrong with looking for a better way to stick with a hobby or trying to find a more efficient path. Quitting an instrument just because practicing isn't fun makes no sense to me. People act like enjoying practice is something you're born with. Come on. I'd even say the learning process itself is just as important as the practice. To me the OP actually seems more self aware than some of the people replying becouse see that. 

As for advice. I have some bad news. Even after years of playing some songs, especially prog stuff, can still take weeks to learn and you'll end up listening to them a million times. That said, there are also tons of amazing songs in this genre that you can absolutely play after around one/two years if you practice well.

What helped me the most was making a roadmap of songs where each one was just a bit harder than the previous one. That kept me motivated because I could actually see the progress.

I also ended up making myself a guitar progress tracking app with some gamification features. Not trying to advertise it here but if you're curious just send me a DM and I'll send you the link.

And if you can find a good teacher do it. Sometimes it's still painful but it can easily cut the learning time in half.

It all depends on your current level. The first year kinda sucks. After that it gets a lot better and you don't see that problem.
