I have too many hobbies. I enjoy them all, but I don't obsess over any of them. They can all cost a lot of money and require budgeting, but not airplane money.
I guess I'm a 3. I'm serious enough to have a dedicated room, but I'm frugal enough to not play in the "Class A" pool very much.
I'm also older and my hearing is what it is.
Better headphone system will probably be a step in the future when we "downsize".
