Actually understanding the word Destiny is still very unclear to me but one thing I know is that even before we were conceived our destines have been established, and so whatever actions and decision we take, it all points towards our destiny.
Sometimes we find it difficult to understand how it works, why we do the things we do even when we don't wish to do it, why we meet certain people at certain points in our life, why different things happen to us at different times; all these links to our fate in life, and no Matter how long it takes, we will definitely arrive at our destines, this brings me to the popular saying that "Destiny can be delayed but not changed".
