On the the keynote sessions at the recent Toastmasters Convention was presented by Bob Hooey - "The Ideas Man". His speech was entitied "The Power of One – you can do and will make a difference" – a very relevent topic to leaders in Toastmasters.
He gave us all a copy of one of his books – "The Power of One". He has also made several books and articles available for free on his website. This includes several full length books on leadership, management and self-development.
I highly recommend some of the downloads – so visit http://www.inthecompanyofleaders.com/TM.htm to grab some of the articles.
