In order to answer this question, one must look at life in metaphorical terms as a blank sheet of paper. When we are born, each and every one of us is about to embark upon a life's journey. Naturally, when we start out on that journey, we have no experience that we can use as raw material for the story of our lives. So our sheet of paper, as it were, is blank when we are born.
As we progress through life, however, we gain more experience, and as we do so, we will find that what was originally a blank sheet of paper has become filled up with experience. In due course, that experience will form the basis of the life story that each one of us will be able to tell.
Even if the journey isn't a particularly interesting or exciting one, it can still form the basis of a life story. What matters here is not so much the content of a story, but the very fact of its existence. In other words, it doesn't really matter what we cover the blank sheet of paper with; the main thing is that it's covered.
And by covering it, we can confirm that we have had many experiences, experiences that may not mean much to anyone else but which have nonetheless shaped the general direction that our life journeys have taken.
