You've given a great example on how people achieve their dreams. Yes, dreams and goals are way too different. Dreams are a succession of images, thoughts, or emotions passing through the mind. While goals are set with a SMART (Specific, Measurable, Attainable, Realistic, Timed) guideline. It is not nice to do bad things just to achieve your dreams. You have to work for it for you to be able to attain it. That's why you need to have a proper goal plan to achieve dream. Dreams are like the top of the ladder, you can't reach the top of it without passing through the first and successive steps.
