I hate my memory

For forgetting things that I want to remember and remembering things that I want to forget! Coming to the first part of forgetting things that I want to remember, have tried so many methods which teach you how to remember things, like...hmm...err..well I can't remember the method! Worse still, I can't even make a conscious effort to forget something that I don't want to remember, because of the obvious reason that whenever I make a deliberate attempt to forget something, ironically, I would be remembering that. ughhh, it's a mess, this memory business, let me just forget that I wanted to remember some things and forget some other things. Now, how am I going to do that?
