Not to sound too new agey but I guess one of my core values (can't believe I am using that term) is to try to have a beginner's mind. Meaning to approach things I am already familiar with as a beginner (hard!) and to always try new things that I know nothing about (easier and often fun). In the context of the studio critique this quote seems to be advocating a similar idea; the studio critique should be one more step in art making, not the ultimate step. That is difficult though, to think about a critique as not being a judgment but more equal with every other aspect of one's process.
