Do you know what a unicorn is?  Yes, it is a one-horned horse-like creature of myth, but more importantly, it is that which you cannot acquire by hunting it.  If you hunt it, you will spend your life in vain obsession and never acquire it.  It only comes to those who do not seek it or ask for it.  Most of the things you want most desperately are unicorns.  You will never get them because you want them so badly and chase them so obsessively.  Usually, to acquire a unicorn, you must do the opposite of pursue it.
