> My highest self-complexity is in my work and main goals. Like composing an orchestra there any many moving parts that need to come together. Hobbies and sports are generally less complex and more simple.

I think that depends a lot on the hobby and the individuals dedication (and ability to devote time) to the hobby. For example, one of my hobbies is I'm working on writing an opera. So that is literally writing for a full orchestra, but with the additional complexity of writing a story and libretto. In truth most of my hobbies can easily get as complex as my job, if I want to take it that far. However, for many people (sometime myself included) the fact that they are hobbies means we are limited in how much depth we have the time to commit.
