It's both work and a hobby. I wood work and a lot of that is hard work but first and foremost it is my hobby. I don't know what your work is but whatever it is it sounds like you enjoy it. Congratulations! Whether you need to make money or not the first best thing is to enjoy what you do.
A lot of things that are hard to do are not necessarily work. Or are they?Do professional athletes, entertainers, authors, etc. see what they do as work as the rest of us who actually go to jobs do?
