Julius Caesar

I know it might be a bit overdone, but Julius Caesar really was an incredibly interesting figure in history.  In his early life, he was in many ways disadvantaged.  His father died when Caesar was just fifteen years old.  At least from his early life, Caesar's is an underdog story.  He could have just basically given up after his father's death, but his ambition was much too strong for that.  Even though Sulla really hated him, he still found a way to gain power, and eventually full control of Rome.  Caesar's story is so interesting to me because he shows us how a person can do nearly anything with enough ambition (and money, to some degree).  His story is also a warning against having ambition at the cost of political connections, as Caesar gained many enemies during and after his ascent to power.
