The biggest challenge is self-financing 100% of everything. Recording costs, studio time, engineer fees, travel costs are all a part of the creation process. Then after the creation, there are producer fees, mixing, mastering, photo shoots, artwork, packaging, artist feature fees, legal fees, clearances, and so on that must be covered before any music can officially be released to the public.
The modern picture of the artist began to form: The poor, but free spirit, plebeian but aspiring only to be classless, to cut himself forever free from the bonds of the greedy bourgeoisie, to be whatever the fat burghers feared most, to cross the line wherever they drew it, to look at the world in a way they couldn't see, to be high, live low, stay young forever -- in short, to be the bohemian.
