Time management is one of the big issues, I think, with most people who make their living outside traditional employment. When you have work, you work on the job (or jobs) at hand. There is, after all, the mortgage to pay... Then, when you ship those mosaics out the door, all the paperwork is waiting for you. Sometimes not so patiently. There are so many administrative and marketing tasks to do in the down time that it never seems like we have time to do art just for the sake of art. I think that's truly one of the biggest challenges of an artist. That time to create just for the joy of it; to develop as an artist, at some point, has to take priority over all of the other tasks. It's the only way that you can really evolve and if it has to happen on the weekends and evenings and you don't get much sleep, so be it! It's worth it.
