    I like the interesting tiny button on Google Homepage: 'I'm Feeling Lucky'. In my view as a rational scientist, 'Feeling Lucky' can be very important, because good things often happen when 'Luck' or 'Serendipity' meets 'Prepared mind'. We know that many great inventions and wonderful creations were born with such magical meeting of Serendipity and a prepared mind of the person feeling lucky at that precise moment. So feel lucky with a prepared mind, and good things will follow.
