Each of us walks on a path in life. Either this path is by his choice or it is imposed upon him. So he lives his life with its sweetness and bitterness, its pain and joy, its success and failure, until he reaches the end of the path.

And at the end of the path: Either he finds that every step he took on the path of his life was running after a mirage that did not materialize, so he leaves that as a lump in his heart and throat, and he keeps asking himself: What happened? Where did I go wrong? Or he feels that his steps on the path he walked on have achieved his dreams and aspirations, or some of them, so he feels satisfied with himself. Or he may be somewhere in between.
