A random philosophical question.

[demonpenguin]

Is there some rule somewhere that states that the thing you desire most must never be within your reach? I mean, seriously. If we are never to attain that which we desire most, what is the purpose of trying to attain it?

Any and all answers are appreciated.

P.S. Why is it that al the really good ideas that you get are the exact moment before you go to sleep, thus you forget them?
