One of the old-line sales mantras is "Think positive." 

Well, on that point,

there's this from  a recent USNews and World Report article:

"A recent study published in Psychological Science found that those with
more optimistic attitudes had better-functioning immune systems which, in turn,
helped them ward off illnesses. Yet far too many of us assume that optimism is
an inborn trait bestowed on a lucky few. That's a completely wrong assumption,
says James Maddux, a professor of psychology at George Mason University. Can
people learn to be optimists? "The answer is an indisputable yes,""

The deeper point for us in this blog: Do optimists (a/k/a positive thinkers) make more sales? From my experience, and from all I've heard, yes.  If you don't think you can make a sale, you're right: you won't.

Go to "Five ways to become an optimist," USNews 

For a different take on that subject of expectations shaping reality, you may want to check out one of my other books ("other" in the sense that it doesn't relate directly to sales and selling).  That is, JOINING MIRACLES: Navigating the Seas of Latent Possibility.

What does "Navigating the Seas of Latent Possibility" mean? How can it change your way of looking at the world and "reality" as we know it?  The website will tell you.
