what is this debate about?

"When it came to first writing this material a couple of years ago, I vividly remebered that experience and my sense of indignation, because it was just so impressive to me that somebody my age (at the time) could have the nerve (and the courage) to focus upon and think about owning a Ferrari and then move in that direction! It was eye-opening, to say the least. But this memory taunted me during my writing because then, and to this day, I could do the Ferrari, yet I haven't. I hear that all-too-familiar inner voice, 'Mike, you don't need a Ferrari! Look at all that's going on in your life: all the travel, investments, and adventure!' And then another voice reminds me, 'Mike, nobody needs a Ferrari. That's not why you get a Ferrari.' Then I counter that I really don't care that much about having one, and the debate continues. So I've still got a tug-of-war going on somewhat. But, I'm an adventurer like you, and the learning and discovery process never ends." ---Mike Dooley Manifesting Change
