It may take you a moment to think of one single profoundly influential experience, or perhaps may take some soul-searching to decide on a simple answer - this is okay and to be expected. If you are unable to answer this question at this moment that is okay as well. This poll will be open for 7 days, you may revisit it at a later time. This question is purposefully oversimplified and is for the sake of a research proposal. I would appreciate your honest opinions.
