I have heard of an Arabic proverb that goes something like this….

“If you think a problem will be solved in your lifetime, then you haven’t taken on a big enough challenge.”

We should have no problem being pie in the sky dreamers who seem to be completely unrealistic in our goals for humanity and existence. If we don’t bring these thoughts of possibilities into the realm of existence by voicing and endeavoring towards them, they should indeed have no hope for possibility.  

Let us all hope and work for something truly worth while.
