Making a dream come true is a long, laborious process. It requires incredible patience and resilience. Choose a dream for which the work is something you can see yourself getting up for every morning, because to make a dream come true you'll have to be willing to work harder and more strategically and with more focus, discipline, and dedication than anyone else.
