Destiny--n. something that is to happen or has happened to a particular person or thing; lot or fortune. The predetermined, usually inevitable or irresistible, course of events. (From Dictionary.com)
Personally, I don't believe in destinies. The reason is, is that there are so many people in the world that may have chances with fate as well. For me, since I've transferred so many times, I have tendency to hold back human interactions because I know that it is "predetermined" to leave this all behind. Which is the reason why I am so great at time management. In addition, destiny and religion goes hand in hand. For example, Christianity believes that the world will end soon, and the fact is, those who do good will receive everlasting love with God in heaven, whereas the evil will burn in the everlasting lake of fire (what a pain!). This is similar to destiny, for whatever you do, you get to have two choices, shall you choose the fire or the love, it is your choice. However, Christians also believe that God is loving and has a predetermined path for every individual, although it seems contradictory, I do believe that God is a figure that people can look up to and adore. I, on the other hand believe there is no "destiny" and you must choose your own path; make your own destiny.

Hail Macbeth!" (Act 1 scene 3) is captivating for a small nobility of Macbeth. Of course he will take matters into his own hands. For this reason, the witches are so important. Whether or not Macbeth does try to murder his authorities, the witches obviously played in Macbeth's part. This is why I believe that if Macbeth lived in modern society, he would be a politician. The witches would be his campaign managers, but they would just tell him, you don't need to do anything, you'll win. It's almost like reverse psychology. However, as we all know, Macbeth does do something, and that was to (SPOILER ALERT) kill King Duncan. (or does he?) This is ACT I scene 3, of Macbeth, where Macbeth speaks to the witches:
