Long ago, Ben Graham taught me that "Price is what you pay; value is what you get." Whether we're talking about socks or stocks, I like buying quality merchandise when it is marked down.
Long ago, there was something in me, but now that thing is gone. Now that thing is gone, that thing is gone. I cannot cry. I cannot care. That thing will come back no more.
I had long ago discovered that when a word or formula refused to come to mind the best thing for it was to think of something else: tigers for instance or oatmeal. Then when the fugitive word was least expecting it I would suddenly turn the full blaze of my attention back onto it catching the culprit in the beam of my mental torch before it could sneak off again into the darkness.
