  5. Authentic Swing speech in The Legend of Bagger Vance
    (Clip I found was choppy, so here's the speech itself) "Inside each and every one of us is our one, true authentic swing. Something we was born with. Something that's ours and ours alone. Something that can't be learned. Something that's got to be remembered." I like to remember that we all have something to give the world, and though those gifts we may give to the world are similar, we show what we have differently, like a golf swing
