I get that you want to be an artist. I want to be an artist as well. Good to know we both are in the same boat.
Science is a useful subject no matter what you want to be. Science teaches you how to reason and ask questions. There are numerous mysteries in the universe waiting to be discovered and science helps us uncover them.
When you are an artist you are giving language to these mysteries and expressing what they mean to you. Like if you make a painting about the mysteries of the universe example how would a black hole look?
You can also use technology as a tool to make art example new media art or interactive installations. So, you are using science to question, technology as a tool to make and art as an expression.
In a way, science and art are complementary to each other e.g. Da Vinci used scientific knowledge is his paintings and inventions.
