In between working on the website and audio for the new SooperSekrit project today, I followed a link to an article that turned out to articulate one of the greatest (and most easily fixable) systemic problems that a lot of us face.
If you are someone who was tracked as "smart" or "gifted" as a kid, chances are good that, sometime in college or in your early 20s, you went abruptly from great academic success to continual, abject, failure, giving you feelings of directionlessness, depression, futility, and worthlessness.
This is not a coincidence. The following article explains how and why this happens. If you were tracked as "gifted" as a kid, or if you are a parent, you need to read this article. This phenomenon happens both with men and women, but with men it is usually less ubiquitous, whereas with women it frequently touches every aspect of their development.
Not kidding, what you read at this link can make a difference of about ten years in your adult life (in terms of career progress and also in terms of success in relationships and hobbies).
Another excellent article in The New Yorker provides more background.
And another article (alas, behind a paywall) from Scientific American covering the issue in a broader and more academic fashion, with good references for further reading: The Secret to Raising Smart Kids
