In my point of view the meaning of this is to be successful someday you have to start little by little until you reach your goal.
For me, this means that you should start at the very least thing and continue perserving to work on it until you reach your aim or goal in life. Of course, it also needs faith, confidence, determination and a whole lot of sacrifices along the way. The road to success hasnt been always easy so you should be prepared of what things might get into your way.
