i've been thinking about that idea ever since my Tulane professor brought it up last semester. the above quote, i believe, calls on both teachers and students to re-frame how we understand "errors" and "mistakes." if we allow ourselves to truly engage in activities that are challenging, then we are going to struggle. that's a fact. but it's a good fact because if our engagement is authentic, then we'll also be developing the skills to meet those challenges. and that's precisely what i love about the above quote. without explicitly stating it, the message is clear: as challenges increase, so does the skill level required; thus, persistent trial-and-error is not only encouraged, it's required.
simply put, if we are going to get from where we are (X) to where we want to be (Y), error must be one of the main sources of our learning. and i think most people (on some hidden, locked-away level) already know this. so i say, let's finally sing what we all know to be true: errors are a key indicator of learning—what else can offer such a rich source of material from which to study, from which to meaningfully reflect? without error, what does the word "better" even mean?
