On the contrary. Leos are ruled by the sun, which is the self. Aries, Scorpio, and Sag (Sag men are shallow and take pride in their looks) aren't too far behind, however. Capricorn too, as they tend to think of themselves as 'wiser than thou'.
Aquarians? I disagree, Aquarians are very down to Earth and humble people, much like the Earth signs Virgo and Taurus. Probably the most humble of the masculine signs.
