from Astronet:
Leo is Fire to the core! Fire brings a desire to create, innovate, and lead. The sign radiates mega-confidence. Of course, the Lion must have an audience. Without applause, what else is there? The fixed motivation adds self-reliance, a characteristic that works well in leadership positions. Leo is a formative energy, with the ability to consolidate and stabilize. Fire can rage out of control, so it helps to balance self-confidence with humility! Leo needs to become a humble but lovable lion. The playfulness associated with Leo can regress to childish demands for attention, as opposed to healthy recognition and encouragement. Leo benefits by allowing peaceful receptivity to surface. The mature Leo exudes big, beautiful heart and sheds sunshine on all who care to enjoy this bold spirit.

Hmmm... I'm a Leo! That explains it. ;-)
