The ideal answer is: "If I got fired tomorrow, I would be doing mostly the same work as before, but maybe less meetings and admin duties."

As an freelance artist for 9 years I can say that you have different type of challenges.

Founding usefulness in your work means everyday questions about balance between stable income and making actually new, innovative, non-trending things. Free market have unlimited possibilities, but making art for money is not my motivation to do art.

Poor artists are real and I slowly understand why. If your passion is creativity, priorities are different, which makes hard to pay your bills, but in same time let you go deeper of meaning. Well... It's difficult to describe it actually.
