Some thoughts inspired by @annemio who has the courage to ruminate in public about the nagging sense of dissatisfaction with her work.
"A pentimento (plural pentimenti) is an alteration in a painting, evidenced by traces of previous work, showing that the artist has changed his or her mind as to the composition during the process of painting. The word is Italian for repentance, from the verb pentirsi, meaning to repent."
Each creation may offer lessons to improve the next. That is why we post on Ello, I believe, not for applause or even for approval, but for the satisfaction of each small improvement, the creation of a slightly better work next time by the accrual of comparisons. We are in it for the learning, because of what we might be able to create in the future.
Comparisons can be odious, when allowed to expand into the need for perfection. Then it becomes possible to dwell on the reality that there are many whose work is better than one's own. Allowed to run wild, such a process will suggest "I do not belong here because what I contribute is not worthy". Ello feeds this, as does the entire art world, with competitions among artists and celebration of those whose work is judged to be the best. Yet any work that can be improved may also be good enough.
Is there room on Ello for good enough? If not, Ello may become an enclave that fails to support the growth of creators, especially those who are in the early stages of development. There is the danger of confusing different with better, of becoming judgmental, rather than merely making judgments. A friend asked me which of his excellent drawings I liked best. Excited by the thought that he might give one of his best to me, I chose one and was shocked as he tore into pieces. "It is best to maintain detachment from one's work" he explained. My lack of detachment had betrayed me.
The most helpful comparisons are those between what one has done previously and what one is doing now: better, if only slightly, perhaps never perfect, but as good as can be at this moment. That just might be good enough. In the end, the competition with oneself, between what one has done and what one might be able to do, is just as important as comparisons with the work of others.
