Yay! Congrats, Julia! This happens to me all the time. Sometimes I write something that I think is horrible, and yet other people love it. Unfortunately, it can also go the other way around, but either way, subjectivity helps.

So true! Others can help give perspective when we are so immersed in something that we can't see it like others would.
