Without vision / dreams and corresponding efforts, nothing can be achieved.
Many times we see a successful man, and start feeling that he is a Lucky man or he is born talented and so on. In fact we are only seeing the visible part of that man, which is very small portion. There is a major share which is not visible and all the efforts are hidden there.
A student who stand at first position, generally considered as brilliant or born intelligent. No one tries to see the long hours study he has put.
Similarly for a rich man, no one knows how many sacrifices he has made.
Remember that without Vision, Hard word and Sacrifice nothing can be achieved.
