One of my friends asked me why do we get shocked when we graduate and discover that we were dreaming?
My answer to her and to everyone is simply:
Experience is a hard teacher, because it gives the test first, then the lesson afterwards.
We need to have a mission, then experience will help us to set the right goals and objectives. As long as you are keeping your vision clear, and determined on your mission, any drawback will be an experience not a problem.
