How true. It's all a matter of mental attitude -- it's all in your mind.
And that is something money can't fix, it has to come from within you. And you will have to actively work on this mental attitude, it will not magically jump into your lap.
This sounds like good advice, because it IS good advice in many cases, and certainly something I need to remember myself! Listening with a positive outlook, focusing on the beauty rather than the failings, looking for the best rather than the worst, this is a pretty good way to look at many areas of life. So no complaint from me there.
However, it's not always the full story. If it were all a matter of mental attitude, being content with what we have and living with our system's faults, the entire area of high-end hifi wouldn't exist and we certainly wouldn't have a forum here. Finding a comfortable spot on the spectrum of neurosis takes time and experience I think, and with it comes a certain degree of acceptance. I've said here recently that I'm starting to move away from buying components for "accuracy" and going full-on into buying for enjoyment. I don't know if this is actually different (maybe accurate is enjoyable) but for the purposes of my ears and system I don't care. But that's another story.
Of course, genuine, long-running problems can actually exist, and part of the beauty of hearing other systems and comparing (if you can leave aside the associated feelings of inferiority!!) is that you can start to identify actual, egregious problems that are destroying enjoyment and hopefully start to address them. Having bought new speakers recently that have increased my enjoyment HUGELY (I'm listening to MUSIC again!), it's nonetheless clear that the one constant problem throughout all this angst is the room. I'm in my third room since I started this hobby, but all 3 have been dreadful in their own way. It's a truism by now, but throwing good equipment into a bad room is a recipe for disaster, and that's a disaster I've been living for some time. Even now, despite knowing this intellectually, I find it hard to consider really addressing it...
