This card shows a man in the middle of a desert playing a guitar. He's dress looks like some kind of old-fashioned minstrel. Maybe he probably travels a lot and lives off his music, but here he is alone simply enjoying the sound of his own playing. He plays for the passion and joy of it.
I think of this card like the beginning of writing a book when it's all new and shiny and I'm riding on the high of the idea before I get to the slog of the middle where I hate the book and want to write something else instead.
The idea can be applied to anything, probably.
I think this card could also be about having more passion than wisdom or skill since he isn't actually playing for anyone else maybe he isn't good enough yet.
