As someone learning to play guitar this is the hardest part for me. The scales are boring and I want to jump to the fun stuff or learning a song. But then learning that song is a similar process. I have coworkers who are skilled guitarists and it is frustrating to watch them because I know they've put in the hours of doing scales. It is hard to stay motivated when the "wrong audience" is yourself.
Then don't. There are many ways to learn to play music. If you just want to learn to play songs then do that. Don't worry about the scales. Instead of learning scales start jamming with some background music. Start to transcribe some solo you like (don't use tabs) and learn to play that way. If you aren't motivated by playing scales then you shouldn't do it. Make sure that it's always about enjoying music first, then…
The most frustrating part is I used to be a section leader when I played clarinet in HS and could borderline sight read at that point. I've forgotten pretty much all my musical knowledge since then (including how to read sheet music), so it has been horribly frustrating to have shadows of memories for how fluent I used to be in this stuff and to have to start from scratch again. That probably makes me much less patient than I normally would be.
