It's hard for me to imagine writing anything without a word processor. The amount of times I would move entire paragraphs, cut words, and the like in just a standard college paper was unreal. I envy the letter writers of days gone by who would draft long letters (any one of them easily longer than any I've ever written) only to crumple them up and toss them into the fire. Despite the frustration of having to throw away something you've spent substantial time on, it must have been pretty refreshing to look at that blank sheet of paper and know you have the chance to fill it up with something even better.
