I find myself often trapped (enticed?) by how fast and inexpensive it is to build software nowadays and also to learn new things. Today, was thinking about 1) what do I actually want to build AND maintain? and 2) what do I want to build and maintain that if I didn't do it, someone else probably wouldn't and I'd be really annoyed that it didn't exist in the world? I dunno, just two current questions I thought you might find interesting, not sure if it adds anything new to the discourse, may be a challenge throughout different parts of human history :-D
