if you view the half cup of water as, half full, you are a possitiv thinker(optimst) also if you view it as, half empty then you are on your own, just on a long thing...a very big parcimst. if you have the choice to think the way you like, and it's takes the same thing(which is time) to think either ways, i mean good or bad, which way would you prefere?
gud luck,post any further reply.
