For every piece of art you are proud of and willing to share with the world, there are likely dozens or even hundreds that will never see the light of day.
Making good art is difficult.
Making art that you are so happy with that you are willing to share it with others is even more of a challenge.
But the bad art is necessary to get to the good art.
The projects that are started and never finished, or that are finished and then discarded or set aside, are an essential part of the creative process.
You cannot make good art without making a lot of bad art as well.
The goal, then, should be to make as much bad art as possible so that you can get to the good art.
The bad art is where the work is.
It is where the learning happens.
The good art, the art that you are proud of, will emerge out of the ashes of your failures.
Make mistakes, make a mess, and make bad art until you realize that there is no such thing as bad art.
There is only the art you are proud of and the art that you had to make in order to make the art you are proud of.
