What is vision???

"Vision" the word which is trembling me now a days...Does this mean I don't have vision...This is not possible I am clear I want to be fit in there wherein "I am THE BEST" something innovative something which is waiting me for years....Does n't this constitute my vision...I do not know the way....does the way to your target is called vision or Destination is called vision? According to me If you know the target you are in constant search of it you will get the target...I am still not clear does I have the vision or not but i know with constant search of it I will get much more than meaning of "VISION"
