I have to admit that I've never really understood that line. It's been explained to me more than once by admirers of Emily Dickinson, but it just doesn't click. My inability to fathom hope in this sense might be due to my non-Christian upbringing. I was never taught that the best is yet to come (in the form of a heavenly future) and therefore, perhaps, I've never been particularly hopeful. In fact, my mother always told me not to count on something good happening; that way you will never be disappointed. Like Woody Allen, I comfort myself with the knowledge that things could be worse, a dismal thought when everything already seems so bad.
I know, I know we should focus on the moment, the little thing that makes us smile, that greets us at the end of the day...blah...blah....blah. But seriously, are you hopeful?
