Years ago I read somewhere that Rivers Cuomo of Weezer has a stock pile of songs. Lyrics and music and melodies and finished products and collaborations and songs sold to other artists...
In fact, whether you like them or not, Weezer has produced two full-length albums this year alone (I know, I know, one of which is a batch of cover songs, but let's be honest, Weezified cover songs often go down so smooth).
Of course not all of our creations will be great or even good, but producing more and more is part of the process that often reveals the really, truly, amazingly fantastic stuff we do release. And yes, your version of ratcheting up production on your projects will look different than my production time.
Overproducing often connects us with a larger tribe, the audience we're seeking to engage in our art, our work. Oh, and by the way, it definitely beats under-producing (remember that book you started 10 years ago).
Create a creative rhythm. Put your creative pursuits to work on schedule, everyday. Produce and then produce some more.
Overproduce, what have you got to lose?
