Ed posted this quote recently and it really struck a cord with me, so I'm going to share it with you in case you don't frequent both sites:

Why do I make room in my mind for such filth and nonsense? Do I hope that if feeling disguises itself as thought I shall feel less? Aren't all these notes the senseless writhings of a man who won't accept the fact that there is nothing we can do with suffering except to suffer it? Who still thinks there is some device (if only he could find it) which will make pain not to be pain. It doesn't really matter whether you grip the arms of the dentist's chair or let your hands lie in you lap. The drill drills on.
