This is one of the best advice for both fund-raising or anything else in life and it's basically the same strategy Arnold Schwarzenegger used to become the "number one star" in hollywood [1] as explained by Steve Chandler:
* ...Then I asked just how he planned to become Hollywood's top star. Mind you, this was not the slim, aerobic Arnold we know today. This man was pumped up and huge. And so for my own physical sense of well-being, I tried to appear to find his goal reasonable.
"Easy, It's the same process I used in bodybuilding," he explained. "What you do is create a vision of who you want to be, and then live into that picture as if it were already true." *
