If you’re an artist, that’s really all you’ve got. You can call it different names (your filter, vision, taste, ears, mind, intellect, etc), but at the end of the day it’s your point of view that sets you apart from everyone else. It’s what defines you.
Everything else is just technique and execution – which, BTW, aren’t even necessary to make great art. Brian Eno couldn’t play an instrument or read music yet he became one of the most interesting and influential musicians of his time.
You may think your ability to execute your ideas is the ultimate manifestation of your artistic expression, but you’d be wrong.
It’s your ability to express your point of view.
