What sounds good to me is what’s optimal in my system.
For me, the saying is,
What sounded good to me is what was optimal in my system, until I learned about how to improve it.
While I don’t want to be on an endless hamster wheel, this is a hobby for me precisely because I am striving to see if I can make things better.
I have been able to improve the sound in the past, and that motivates me to keep trying -- because it’s fun, not because I have a "grass is greener" dysfunction.
