I do best when I shoehorn creativity into my job, and there usually is some opportunity to do so. It helps make a presentation more interesting, or a project more real if there is some humanity injected into it. At least for me.
When I was playing music, though, it was different. It was my vocabulary, not the undertone or nuance.
I think most creative people come to terms with "making a living" but it's important to me to keep using this muscle, however atrophied it has become.
