Alexander got his daring quality from Phillip and got his seriosness from Olmpias
The only thing Alexander wanted to do was achieve great things
Because of Phillip's death Alexander was immediately announced king
      Alexander was born a year after Olimpias and Phillip II were married which was in in 357 B.C.. Alexander probably took Olimpias's side of the family because of his unnatural seriousness. He did not do the usual things that other boys would do like drinking. Alexander also probably got his beautifulness from Olmpias who was supposed to be killed from 200 soldiers, but as the story goes, once they saw her, they left without hurting her. Alexander did not just get qualities from Olmpias though. He also got the quality of daring from Phillip, something that he needed in battles. 
      The only thing Alexander wanted to do was achieve great things. He was obsessed with this and it showed when his father had conquered some city and Alexander said " Phillip, my father will have everything and I won't have anything left to conquer!" Alexander's first experience of power was at age 16 and was because of Phillip fighting at Byzantium and Alexander being called to Pella to be king in the time of his father being away. Many people didn't think Alexander was ready. After all, he was still learning grammar and arithmetic, but Alexander treated this job like he had been working at it for a long time, and proved them wrong.
       At 337 B.C. Phillip saw another woman. He was tired of Olmpias with her pet snakes (it was part of her religion) and her cold premium ways so he decided to divorce her and married this new woman. Olmpias and Alexander were very worried about this. If Phillip had a baby boy with this woman he might name this son his heir (a person who will take over the throne after the king dies). After awhile Alexander couldn't take this stress anymore and said to Phillip one night "What am I then? Worthless?" Phillip was very drunk at the time because when he got up and lifted his sword in the air, he then fell in the middle of the room. Very angry Alexander said "Look at this!" He is trying to march from Europe to Asia and he can't even walk from one couch to another." On the last events of the day of the wedding for Phillip he was murdered by one of his body guards. Some people say that it was Olmpias  who plotted the murder but it was never proven. Immediatly after the wedding however, there was a new king: Alexander. Alexander had high expectations for being king but he couldn't of expected what he was going to do after all, he would conquer almost all of the world. His father had just set the stage for him.
