For me I feel a lot of this is combined; the things I do for fun, a hobby, is art. I love to start with a blank canvas and make something out of it. My Passion is also art, it consumes my thoughts, it makes me happy and I'm always thinking of new ways to further my skill... my dream profession would be a concept artist! Someone who creates the foundation for a finished product, such as a movie or a game.
If I was to think of different things, a hobby could be gaming, it's what I do between art to chill and relax, and gamings what got me interested in concept art, seeing the stages of creation before the finished product.
But yes, I totally agree on the topic of envy. I have people tell me they're jealous of my talent and it makes me really uncomfortable, I started drawing on walls in crayon, potato people with stick arms and smiling faces, I wasn't born like this, I worked for it.
