I'm a musician with a day job. This is a widely familiar approach to a music "career." I've learned to satisfy myself with playing for a live audience and not trying to do any kind of recording or publishing. There are things that a "day jobber" misses out on, such as more elaborate projects that require rehearsals that are held during the day, or anything involving travel. On the other hand I have the freedom to play fairly esoteric music that is not commercially viable.
