A speech should always be heart-felt, personal and to the point, and Hillary's final speech ticked all of the boxes.  For the first time she was speaking as herself.  Her warmth, genuine passion and love for what she does shone through and it's these qualitities that gives a speech the desired impact.  If you are not connected with what you are talking about how can your audience be?  

Every good speach has a structure, and Hillary's definately had this too.  There was a strong intro and outro - with the outro being the chat about young girls - the bit the press took hold of.  

Too many people - both politicians and also professionals write a script that lacks any personal language or message - but as Hillary has proven the best ones are the most personal ones.  Your speech should be as unique as you are, and Hillary's final speech felt like only she could have said it.  A great end to a long campaign and one that will stand the test of time.
