There's always a potential career for an artist. It takes a lot of talent, hard work, diligence, and healthy dose of luck and timing.

As for being a stand-alone songwriter who writes entirely for other artists (me), those days are over for the most part. The money just isn't there to make it a viable profession anymore.
