I sometimes giggle to myself when I hear the term 'Influencer'. I created my Remote Influencing (RI) system back in the USA in late 2002. I had bought the domain name, remoteinfluencer.com in 2003. I ran a .com web site with the aforementioned domain name for quite a few years.
I had my book self published in 2008. The title of the book is, The Remote Influencer 2. I didn't write 2 books. It's a long story as to why I had chosen the title with 2 at the end of it. The important point I am making is that I have used influence and influencing way before the term became popular. This is why is is important to document your work and your ideas. Otherwise it's just hearsay.
