Take a look around you.
Chances are you're in a house.
Guess what someone designed your house. Someone designed your computer. Someone designed your clothes. You know that tablet? I'm sure there was a small team who designed the look of that.
ANYTHING that you see, touch, use has literally been someone elses design.
You know those cubicles that you're going to be stuck in for 40 years? Someone designed that too. Your favorite movie? A bunch of creative teams built that.
To say that art isn't important is to be completely ignorant to the world you exist within. Anything you interact with: the chair you sit in, the desktop UI, any game you can think of, product packages, clothes, shoes, cars, houses, weapons, utility items, utensils, your bed...Everything has been created by an artist.
Art is literally everywhere, and yet you choose to leave this world where your ideas are not only valued, but consumed by the public. Artists create trends, styles, and brands. While just developing pretty illustrations is totally fine, an artist can literally be the creator of anything. UX designers literally create experiences. It may not seem like art, but you are still creating the way someone interacts with something else.
I'm sorry you have to go, and you won't be missed. Sure artists arent going to cure cancer, nor are we going to mix chemicals together. But artists create experiences, and that alone is much more powerful in the long term.
Art is worth it, but it isn't for everyone. Peace man, go into business management or head towards med school. Art can be compared to these other professions because of the amount of training and influence it has on the world. Anything else and you'll be REALLY wasting your life.
