“An even more extreme example of a onetime grand gesture yielding results is a story involving Peter Shankman, an entrepreneur and social media pioneer. As a popular speaker, Shankman spends much of his time flying. He eventually realized that thirty thousand feet was an ideal environment for him to focus. As he explained in a blog post, “Locked in a seat with nothing in front of me, nothing to distract me, nothing to set off my ‘Ooh! Shiny!’ DNA, I have nothing to do but be at one with my thoughts.” It was sometime after this realization that Shankman signed a book contract that gave him only two weeks to finish the entire manuscript. Meeting this deadline would require incredible concentration. To achieve this state, Shankman did something unconventional. He booked a round-trip business-class ticket to Tokyo. He wrote during the whole flight to Japan, drank an espresso in the business class lounge once he arrived in Japan, then turned around and flew back, once again writing the whole way—arriving back in the States only thirty hours after he first left with a completed manuscript now in hand. “The trip cost $4,000 and was worth every penny,” he explained.”
