My parents were huge collectors of ...stuff. Not quite hoarding, but in the same neighborhood.
I was for a while, too, simply because of how I was raised. But as my own home filled, I clearly noticed how less happy I was becoming. And when my parents passed, the work of dealing with a full home was, frankly put, awful.
I purposefully have changed my hobbies to things like music, cooking, gardening. Gaming, too. You can practice a musical piece a thousand times- it doesn't add to your mess. Cooking fulfills an immediate need, and it's been my experience that quality food as a gift is more appreciated than almost any physical artifact. And plants bring their own joy, without continuously taking more space.
My mother once told me late in her life to spend my money on experiences, not things, and I think about it often. She was right.
