Spoken like a champ

Our spoken words can be powerful, inspiring, informative, boring or cutting.  We use our voices every day to communicate something.  I came across this short video which has contains some solid advice on what we can do to make the world a better place by what we say and how we say it.   I didn't find anything revolutionary here, but I think if I were able to follow these guidelines more closely, it would be revolutionary for me and the people I am speaking with.
