"I don't want to be just one thing. I want to be multidimensional"

This quote by Billie Eilish is all about turning down the conventional concept of being pigeonholed into one career or identity. Eilish thinks that people have the capacity to be complex and have skills and passions in a variety of different locations. She is rejecting society's expectation that individuals must pick one career path or stick to one talent, and instead promoting for a more different and varied method to self-expression. This quote also talks to Eilish's own innovative procedure, which often integrates a large range of musical genres and influences. In general, the message here is among embracing complexity and turning down limitations.
