For the rest of your life to be as meaningful as possible, engage in spiritual practice if you can. It is nothing more than acting out of concern for others.

Destiny ... a word which means more than we can find any definitions for. It is a word which can have no meaning in a mechanical universe: if that which is wound up must run down, what destiny is there in that?

Each man has his destiny, though some men are undoubtedly "men of destiny" in a sense in which most men are not.
