All the stuff that was embarrassing about your journey with your work is going to make you great.
I used to think that famous creative people must have been born that way. The doctor pulled them out and just KNEW oh this one is destined to have an easy life and be artistic and beautiful. "I can tell because of this artist's palette-shaped mole." But nope, even the successful people have had to walk through whole fields of embarrassing situations, bad attempts, terrible paintings, cringe-worthy wrong notes, dumb ideas, awkward situations, self-doubt, benders, regretful nights at parties, rotten relationships, all of it.
Successful people DO get something right though:
They are determined to be resilient despite funky circumstances. They see the failures as PART of the path, NOT as a sign from God that they weren't born good enough.
Successful creators count the stumbles as part of the path towards understanding their work. Thanks to those bad notes, terrible songs, ugly paintings, embarrassing videos, etc. they know more about what works and what doesn't than someone who refuses to stick through the dance. Successful creators know more than the ones who bail or make excuses when they hit a wrong note and their embarrassed egos can't hang with it.
If you think that successful creative confident people were simply born beautiful and rich and that's what got them to where they are you might be right about a TINY percentage of them, but you'd be missing the main secret that brings most successful creators their success: tenacity to endure the embarrassing, awkward, and dumb stumbles.
If you are an independent creator or want to be more creative and confident with your work, dig in with curiosity and tenacity.
Let the stumbles come. Stumbles are still forward movement
Come at the work you love (or want to love) with the tenacity of someone prepared to stumble through some awkwardness.
That is the tenacity of a successful creator.
