There is a really difficult mind-space for people that hold themselves to high standards when, while learning a new trade or skill, they realize what the best work looks like (i.e. what they desire to make/do) but are unable to perform at that level yet. Often the gap is because these people are still learners, operating in an area where true mastery requires years and years of experience. For some reason, though, it is hard to accept that apprenticeship equals failure on an intrinsic level, that if we don't make bad work there is no way to learn how to make good work.
I know this. I can even write about this. But it is SO HARD to embody it, to release the pressure I self-impose to knock it out of the park with every project that comes along. I want all of my work to be amazing, not necessarily for the praise of others (although this is definitely nice, however another minefield in and of itself) but because I am used to being at the top of whatever I'm doing. I know I'm capable of doing impeccable work, and it's hard to accept that it's okay if I can't right now, for whatever reason, in whatever capacity.
I think people doing jewelry or metalsmithing at a high level are particularly prone to this issue. Our field is all about perfection, precision, doing it right the first time because often that's the only option lest you go back to square one with a particular piece. Our eyes are meticulous. We see all of the flaws. Making can be maddening. We get so invested in our work, put in so many hours... It becomes especially hard to look at a piece after blood and sweat and tears (literally. really. i cry nearly every week and can't feel the tips of my fingers) when you know certain things should have been done differently and/or better.
I need to remember - I think all of us in the progam could stand to remember - that other people don't see jewelry through the same discriminating eyes as we do. Other people see the beauty, the creativity, the materials. Not that this is license to do shoddy work, but to remember on those pre-critique mornings that someone out there will think this is the best. piece. ever. made.
