So your savings or other passive income provide for your needs when you hobby happens to 'not' earn money? There are a lot of people in my circle of friends who have reached that point of not "needing" to work in the sense of putting food on the table or paying for things, but working on things they enjoy because they have things to do which are fun.

'unemployed' tends to get people who don't know you wondering if they should feel sorry for you or not, 'retired' seems to bring up images of rocking on the deck chair and playing golf during the day. I feel like what you are doing is somewhere between those two.
