Believe it or not one of the most important covert persuasion principles is self confidence.
I have always noted throughout my sales career that when I’m full of confidence I get better results.
In fact, I had a little practice that whenever I landed a big sale I would immediately go and try to close some other deals that I knew were close to fruition. I figured “nothing succeeds like success”.
I read this post today from Geoffrey James in which he helps a reader with some self confidence issues, it’s well worth a read.
