I have been doing unpaid hobby projects for forty years, so I have an opinion: Sometimes there are things that I would like to work on at work, but there is no official support.

I co-write a book on UML, and now I don’t particularly recommend it. The only type of UML diagram that I occasionally still use is Sequence Diagrams.
