A dream according to Webster is something that fully satisifies a wish, a strongly desired goal or purpose, or a visionary creation of the imagination. No matter how you define it - dreams are not impossible. If you dream it up, then it's possible. Maintain the mindset, no matter how rough things may get, that anything is possible. Instead of asking yourself why not, remain focus and do things within your power to make it happen. What if you do this or that - your dreams could be within reach.
