▲ Different Moods, Different Styles of Thinking ▼

Jonah Lehrer, broadening the discussion:

And that's why relaxation and happiness are so helpful: these moods make us more likely to direct the spotlight of attention inwards, so that we become better able to eavesdrop on the quiet yet innovative thoughts we often overlook. (That's why so many of my best ideas often come during warm showers.) In contrast, when people are diligently focused (and perhaps a little melancholy), their attention tends to be directed outwards, towards the details of the problem they're trying to solve. While this pattern of attention is necessary when solving problems analytically, it actually prevents us from detecting those unlikely connections that lead to insights and epiphanies. (William James referred to insights as emanating from the peripheral "fringe" of consciousness, which is why they're so easy to ignore when we're staring straight ahead.)
