I just read a post on line from an artist who says she sometimes doubts the value of her work and the time she spends making it.
I was surprised, frankly, to hear any true artist say this. In a nutshell, the value of any artist's work is based on the affect it has on the artist's psyche/soul/well being. Of course this is just my personal opinion, and one that has taken many years to arrive at.
I used to think (20 years ago?) that it was a waste of time to make art that did not sell. What would I do with it? Should I give it away? Donate it to charity? Burn it? But it didn't take long for me to realize that sales are not the be all end all of being an artist. The paramount reason for persevering is to improve, learn, and improve some more. The less you care about sales, in my experience, the more you will sell. As for the ones that don't sell? I have done all of the above with them. I have even gone back and improved them and they still don't sell. Ha ha.
There is a certain sense of freedom after you discard old work that is below the caliber of what you are presently creating. For me, it signifies that I have, indeed, grown as an artist.
I hope that you, too, whatever your work might be, will try clearing your space and allowing creativity to blossom.
Below is a piece I threw in the dumpster that was painted four years ago. I'm proud of the geese, but the rest of the painting was mediocre at best.
