There is an old motto that runs, "If at first you don't succeed, try, try again." This is nonsense. It ought to read, "If at first you don't succeed, quit, quit at once."

But the people who do go to a lecture and who get tired of it, presently hold it as a sort of grudge against the lecturer personally. In reality his sufferings are worse than theirs.
