How do you get Happy as an Audiophile?

I agree with many who have said MUSIC is the primary goal.  But first I believe you have to be in a receptive state of mind for the music.
If your primary goal is sonic satisfaction,  If you want merely to hear how good your system sounds, is that enough?  I believe it’s a dead end. It’ provides limited gratification.
Whereas music affords an infinite variety of delights.

The 2 goal music and sound satisfaction are attainable at low cost but and there is a BUT, you must learn to controls mechanical, electrical and acoustical working dimensions... Is it only my opinion ?

No it is my experience... Is my audio system perfect ? Not at all... But it is enough good to make me smiling at any COSTLY upgrade.... Diminishing return law exist... Especially if you use acoustic but also psycho-acoustic control to optimize your gear/room/ears relation...

i say that to give hope... I never want to live with music in an unsatisfied sonic clothes...I only had the time to solve this problem after my retirement... i will never upgrade nor be envious again ....Think acoustic to begin with at least...

For me a positive outcome of this hobby, and one I never envisaged before getting into it, is forming friendships with other audiophiles. This includes some I've only interacted virtually (messages, phone, text, etc.), and some I've had the pleasure to meet in person. Either way, it's great to talk to someone who shares your hobbies and passions without worrying about politics, religion, race, etc. 

Positive psychology certainly has its fair share of detractors.

To ignore the causes of anything is one highly dubious means of attempting to build anything substantial.

Besides, perhaps the terms happy and audiophile are mutually incompatible?

Perhaps once you're happy (ok, satisfied) you're no longer an audiophile. You're merely a music lover.

Positive psychology certainly has its fair share of detractors.

Yes it does.  Some of it for the methodology and math, so I don't wish to make this about whether positive pscyhology works so much as about being happy as an audiophile.
