For every hundred words I post there are another five hundred no one will ever see.
Not all paintings hang on walls. Not all music is played on a stage. Not all words are part of the final book or post.
It doesn’t make you any less of an artist or writer or musician.
I’d argue that those messy words are almost more important than the final product. They clear the way for the good stuff to come out. I’ve often found that my best ideas come after I’ve written three bad ones. You just have to keep trying.
