I assure you, at least for me, each time I draw or paint, I experience some level of deep anxiety or insecurities boil to the surface.
It may seem easy when a song is already written to learn to play it, but the process of tuning in the universe's messages is a different story.
Sometimes it's so overwhelming that it feels unbearable. Whenever I see big wave surfers put it all on the line, I think to myself “what's the artistic equivalent” of putting it all on the line? Creating so purely that it leaves you in a vulnerable mental state? Allowing yourself to be held down until you come back up ? Being so unfiltered that you invite criticism?
My wife can attest to this artistic battle when she walks in my studio and I'm slumped over or I walk upstairs from my studio and I look like Superman after being exposed to kryptonite.
Maybe it's just my “process”. I don't know how many other musicians and artists experience this cyclical swing, but I need to just allow it to be.
Sooner or later, if you just hang on, greatness reveals itself to you and those are the glimpses of pure greatness itself that make the struggle worth it.
