Certain things I know not to get rid of. I am an awful musician but I know I will keep fooling with it every now and then. I won't get rid of my little MIDI keyboard or my walnut penny whistle. I don't play the whistle well, but once I became a wooden whistle/flute maker; I was terrible at it and sold most of them on eBay as toys or props. But I made a few that were okay and one that was perfect. I have that one.
I thought woodcarving was going to be a forever hobby but I need to sell off those dusty tools. Arthritis is a contributing factor. I may take up clay sculpting instead.
Drinking was one of my hobbies but I gave that up.
