You say I dream too big. I say you think too small. No dream is too big to try for. Achieving the impossible is possible when you are motivated enough and you work hard to make a dream come true. Through history the human race has shown that nothing is impossible when someone has enough passion to work tirelessly and the vision to see what could be.
If you are going to dream why not dream big? The most successful people in the world are successful because they had the nerve to think big. If you think small then you will reap small rewards. When you dream big you can change the world with enough perseverance and the end goal in mind. Small people think small, and they live small lives that do not stand out in any way. Dream big, and keep trying to fulfill your dreams even if you fail at first.
