The Secret is all the rage, apparently. Haven't read it myself. From what I can gather, it is one of those "focus on it and it will come to you" books. I will grant that if one is thinking about something with intent, one will just naturally do things which might help that along. Beyond that, there's too much counterevidence.
If thinking really hard about something and imagining it in detail made it happen, or even was much help in making it happen, then I would have slept with a lot of girls in high school and college. My college had 4,000 students, high school had 2,000... heck, that's 3,000 girls right there. And don't tell me that you have to be more persistent and focussed and not so scattered to make it work. At the highest cutoff you can set, there would still be a dozen girls on that list.
Also, every guy in America would have had a brilliant sports career. There would be so many of us who hit the final shot with a few seconds left that it wouldn't be worth mentioning anymore. At least 50% of us would have won a lottery. Been in a movie.
On a more serious note, let's see how happy everyone is about explaining this secret to starving people in Africa.
Just think these things through, people.
