I have very little structure in my life, and that has been the case since forever. That said, my wife maintains some level of structure, so at least sleep times are more controlled. I wouldn't say there is a better way of living, but there is always a better way of living for you.

when my grandmother died it became quickly apparent that she had spent her married life keeping a lid on my Grandfathers undiagnosed mental health problem by imposing a strict routine on the whole family. My Dad had to spend a bunch of time establishing a routine my Grandad could handle himself. It went fine except we had to make sure we went to restaurants that were serving that day's meal. He always had Shepherd's Pie on Wednesday, so that's what had to be eaten, regardless of location.

Lovely man.

Anyway, I was thinking of the cultural enrichment enterprise, and found that Portland has a bunch of museums that are free, either sometimes or always. The Safety Learning Center and Fire Museum might be more exciting than it sounds, but Portland Art Museum is on there.

For cheap tickets, Goldstar might be useful. I can't swear it, but a friend vouches for it.

Edited to add: It occurred to me that you might be in Portland, Maine. If that's the case then this list has a bunch of freebies, but most importantly the International Cryptozoology Museum looks unreal. Like, literally.
