Time passes no mater what we do. The earth will continue in its orbit around the sun. The hours will pass and the seasons will change. How peculiar time can be though. We perceive it as valuable because we only get so much of it, yet for many occasions it takes too long. Sometimes we rush time and others we try to enjoy it longer.
It is strange to speak of rushing time or slowing it down when in fact, it's constant. Time passes at the same rate no matter how it is perceived. You may experience an hour in a waiting room versus an hour playing your favorite game differently but both hours contain 3600 seconds.
When making your dream come true, don't worry about how long it will take. Instead, get lost in your dream. Completely involve yourself and work to make it a reality. You may find that the time it takes to accomplish your dream seems shorter than it really is. Remember, the time will pass anyway so you might as well put it to the best possible use to accomplish your goal.
