We keep a shared note that has the date and link to stuff that we might want to do. I used to love live music but not as much anymore. So she we will add shows she’s interested in and also look for touring comedians. Most of the other stuff above is mine.

We’ve also started watching shows together that one or both of us missed (or rewatching something). Curb, Sopranos, the Wire.

I also plan little weekend trips here and there.

Honestly; we have a ton to do and end up missing a lot just to relax and enjoy the quiet.
