THE GAP by Ira Glass from frohlocke on Vimeo.
It explains exactly my problem, the reasons of my self-doubts when it comes to creativity. And luckily it offers a way to change it too: don't give up and quit, but just continue creating your art.
It sounds so simple.
I should really watch this every single day so that the message of this video replaces all my self-doubts. :)
