I am sure there are other sins that one is capable of committing, but I can't name them off of the top of my head right now.
Arts careers have reputation for being flighty, but that comes from the fact that artists have real struggles in making a living. Most imagine they can overcome that -- but the invincible feeling drags them toward discouragement.
There are many jobs in the arts, and lucrative ones as well; but the odds are lower for stable income than other professions. It is less predictable.
These days, there are craftspeople making a living with an online business, but similarly many investing a lot of time and holding onto inventory.
Museum curators, retouchers, art agents, illustrators, web designers, jewelry makers, activity directors, youth workers, portrait artists... but some of these do not have guaranteed or adequate income. Well-paid animators work on short contracts, and then are left wondering where the next job will come from.
High-end painters may make thousands from the sale of one painting, but then spend thousands of hours on paintings that fill up the house unsold.
There are jobs that now expect designers to shoot and edit video, code web pages, use CAD, be fluent in a dozen software packages, know how to storyboard and select materials and market... for a couple dollars above minimum wage. (Or exempt from overtime.) Ad agencies pay higher, but expect more time and a fast pace.
Teaching is continually wobbly as district budgets squeeze arts teachers into half-time roles, multiple schools, or working from rolling trays. With no budget for art supplies for hundreds of students per week.
College teaching averages 50% or less faculty working on per-course contracts, with no benefits or job security. The full-time arts faculty make less than other disciplines, because they do not draw in research funding.
Some artists who have tried and struggled feel like this:
Hosea 8:7 For they have sown the wind, and they shall reap the whirlwind.
Ecclesiastes 4:6 Better is a handful, with quietness, than two handfuls with labor and chasing after wind
(But then he writes that all aspiration and labor is ultimately chasing after the wind.)
Going into the arts can be appealing, and be a pleasant way to make a living -- but it can also break a person's spirit over time.
