Who Discovered America?

As a little child, I remember asking my mother where is America. She said that America is the remotest place on our planet. In the place as far as the eye can see.
I was too young to ask many questions. I believed. I didn't know that America was a continent. I was thinking of it as the most amazing place, where waterfalls are everywhere, and golden fields are blooming with the most beautiful flowers.
I remember me, laying on the bed and day-dreaming about this place. I imagined me taking an airplane to America, landing there and touring this place.
I was getting a little older, old enough to read by myself. Fed off with ideas, I opened the encyclopedia, searching for some materials about this place.
Then I realised that it's a continent made of many countries. The northern one was my dream-land; The United States of America. I was amazed by the name of this place, or its shortcut – USA. What a name it was. What a joy saying these three letters, one by another.
Every letter was like another sense of this magical place, filling all my sensors with such an intoxicating rush, which didn't let me go. As it was the only thing that was running across my mind, paving its way through math, physics and all the other balderdash which school has personified inside my mind.
United States was my legendary dreamland, full with glamour and precious light.
As I had my first chance, after ending the military commitment, I was taking the first flight which took me to America.
All I could have heard inside my mind was only excitement, which couldn't be turned off. Divine emotions were taking control, while the plane was getting closer and closer to its landing strip.
I was there; in my land of make believe.
I looked both sides, wondering what is there. I couldn't see any of what my imagination had created for me. What had happened?
But, as I was told in my childhood, I didn't charge the book by its cover. I took the bus to the city where I was planning to stay. I was visiting everything that was marked in my map.
There weren't any golden fields, At least not as I imagines them.
There weren't any waterfalls, where water is paving their way through the solid rock; nothing at all.
America was a failure for me.
Imagination has beaten the reality.
Sometimes I wonder what is the exact power of our ability to think, dream or assume. I think it's endlessly.
