I am really sorry to hear about your journey. Mine has been similar in length and certainly intensity. However, I am retired and 73. My journey has been exactly the opposite. It represents the best investments I have ever made and has brought me endless joy along the way.
I traveled extensively throughout my career... first as a geologist when I would frequently spend 8 to 10 hours a day driving... so I had a top of the line headphone system for days (the Sony Walkman Brick with Dolby C), an amazing portable system for my motel room (three weeks in the field, one week home), and an evolving main system and record collection at home.
Later as an executive I traveled extensively globally and used my evolving portable headphone system. While further developing my home system.
Before retirement I did a big upgrade in case I could not afford another after... really great. Fortunately, after retirement I was able to do a much larger upgrade, achieving the sound I never thought possible. One key was in my fifties and sixties was season tickets to the symphony seventh row center that helped me calibrate my ears to real natural sound.
Now in retirement my system gets two or more hours of use and is one of my most prized and fulfilling time each day. The culmination of over fifty years of study and investment. This pursuit has been sooo rewarding. I am very fortunate.
