It's an up and down journey, some stuff is way better than others, but stick with it, and by the end you'll be glad you did. There are some legit amazing stories that get told along the way.

Firstly, condolences on your loss. Hoping that all of their weird and fantastic stuff finds new homes to be appreciated in!
