The developers and the saviors of this world are those that dare to dream. People that still believe even when all odds are against them and point to failure, those are the people that bring innovations to the world we live in.
The visible world is sustained by the invisible or as some will say the spiritual controls the physical. Humanity cannot forget it's dreamers, their names are forever written in the sands of time. Many of us have heard or read about the I HAVE A DREAM speech by Martin Luther king Jr which was given during one of the greatest crusade for freedom in the American History and I'm pleased to say the dream of that great man became a reality and one event that stands as a symbolism was the emergence of Barrack Obama as the first ever black president of the USA. For many of us that haven't heard the speech before I have added the audio.
Today we have the noble knight 
Martin Luther King had obstacles and he was fighting against a seemingly greater force but that did not stop or prevent him from dreaming, having a vision and pushing forward his ideals. He who cherishes a beautiful vision, a lofty ideal in his heart, will one day realize it. We are products of our dreams and visions. The greatest achievements were but a dream at a certain point in time, great minds are not scared of dreaming no matter how impossible it seems at that point and they go ahead on a mission with their dreams as their vision to conquer.
Your circumstances at present may be uncongenial, but they shall not long remain so if you but perceive an ideal and strive to reach it. In essence what I am saying is that your present circumstances may be unfavorable for the kind of dreams and visions you have, you might be going through rough times but if you don't make moves to make things better you will remain in such condition. As humans we should always strife towards perfection even if we can't attain it, so if we should fall short at least we should have conquered some heights.
What you will become is based on the visions that you glorify in your mind, the ideal that you enthrone in your heart and the dream you live your life by.
