Bad logic in that article - they started with millionaires and worked backwards.
So millionaires see the glass as half full, and an opportunity and movie forward - they don't mention out of a random sampling of a thousand people, there may have been 999 who saw things that way (especially depending on how a survey was worded), moved forward and failed.
As for the 3 percent of the Yale class of 1953 who wrote down life goals who ended up controlling 90% (or whatever, I forget) of the wealth of the class of '53 - why 1953? Why one year? Is that the only year it worked?
Bill Gates was what, the Harvard class of 1980, somewhere around there? Did he write a life plan? or can you just as easily end up saying "Change your name to Bill, because everybody named Bill from the Harvard class of 1980 ended up controlling 99.999% of the Harvard class of 1980's wealth".
Yes, I know, he dropped out of Harvard - I'm talking about the class he would have been - but if you don't like that, you can also say "Drop out of school - the dropouts from the Harvard class of 1980 ended up controlling 99% of the wealth of all the Harvard graduates combined".
Bad logic to that article.
