Invisible Ink (a revelation of sorts)

I had a revelation of sorts. I can't hand-write anything substantial. Because, it seems as soon as I commit anything significant to paper, with pen, the passion instantly evaporates, as if written in invisible ink. Which explains why I have a trunk full of notebooks; thousands of hand-written pages; all written with heart-felt intent; some quite good; but, as soon as I attempt to transcribe the words to computer memory, I am overcome with indifference; the words lose all meaning. And this is a revelation of sorts, because while I am only now discovering this fact, I don't really know what I'm to learn from this. I can type, revise, edit, reconstruct, reassemble; write in stream-of-consciousness; create from whole cloth a complete and satisfying piece of work, with a keyboard; but, alas, not with a pen.
