Self Control = Success?

Here's an article that makes me cringe a bit as an unorganized and often attention lacking mom.  I heard it on the radio today...all about how if your preschooler shows quality self control when he is little he's sure to be successful, whereas your less than controlled little one has a higher chance of being tossed into the slammer.  Ahhhh! 

Now, I realize these are generalizations and studies blah blah blah but don't they know the internal anxiety they cause when these scientists toss out such serious consequences via the radio waves?

You know I'll be reading it, and surfing the studies for a while.  At least until something more interesting comes along and I'd rather do that....What??
