It is about seeing your goals to completion and being willing to make sacrifices like giving up free time and energy when necessary. To accomplish your dreams you must be prepared to put aside everything else and commit yourself fully to the task. In the end, the rewards that come from achieving a dream can be very fulfilling and worthwhile.
