What was Cleopatra's biggest goal in life?

Cleopatra's main goals were to be the sole leader of Egypt and to expand the kingdom's land area.  

Cleopatra took the throne of Egypt at age 18.  She also shared the throne with her younger brother.  Soon there was conflict between them.  She fled to Syria and established an army there.  Her goal became to take back power of Egypt for herself.  She wanted to be the only ruler of Egypt.  She soon met Julius Caesar.  He used his resources and helped her to fight to regain power of Egypt.

Years later, Queen Cleopatra turned her attention to gaining back the eastern empire of Egypt.  Modern day Syria and Lebanon were part of this land area.  This plan became less important when the Romans threatened to claim parts of Egypt for their own.
