You're supposed to try, try again. As optimistic as that concept is, some things that one attempts (think of a man who likes a woman who doesn't feel the same way) should not be tried again. He asks her out and she says no, if he tries again and tries again, that makes him a stalker. (Please don't read this as a sexist node, it was just an example that works very well in this case.) And I'm the type who believes that the more you try and fail at something, the worse it looks for you. I prefer the advice of the man who is truly a sage in our time, Homer Simpson: If at first you don't succeed, destroy all evidence that you tried.
