Query: Well, I was disappointed.

I saw this on Oprah while I was job hunting and I thought it was an interesting idea. Unfortunately, it's superficial and simplistic and has no real substance. To say I haven't won the lottery because I'm not living my life as though I already had won is both ridiculous and dangerous. My common sense prevails and I've kept my job and resisted the urge to buy a condo in Waikiki. Based on that, according to this book, I will never be filthy rich. And that's probably a pretty safe bet.
