The greatest sense of all

A sense of style, however skewed, is a must to be cool. A sense of the theatrical to lift the dourness of routine will leave your life embellished. A sense of timing – whether with a compliment, joke or tricky dance step – will set you apart from the ordinary.
A sense of the spiritual, the fact that there are mysteries out there unanswered but within our realm of experience, will evolve you.
A sense of beauty, whether it be art, people, poetry or music, will humble you.
However, without common sense all of the above are pretty much useless.
