Money !
As we are growing up, if not earlier, most of us are hit by the reality of money. That we need to make some to survive... and a little more to make life a little better and so on.... Until we grey a little (or a lot :)) and figure out money will never be enough, unless we begin to think that it is ! I am currently reading Going Postal by Terry Pratchett . The characters might appear to be unreal, or is it the world surreal (!!!), but what they say makes a lot of sense... Here goes an extract : Money in not a thing. It is not even a process. It is a kind of shared dream. We dream that a small disc of common metal is worth the price of a substantial meal. Once you wake up from that dream, you can swim in a sea of money. What says you ?
