The drive to do whatever.

How can we as people not have any ambitions? Without ambition we’d live in a world of complete nihilism. We need to have some sort of drive or purpose to keep us going; otherwise the world would fall on itself. Whether it’s the greed that you see in people to make money anyway they can, or the empathy to help people, we need a drive. This drive helps us advance, gives us reason to improve and expand. There are dark sides to it however; it is not a system to make everyone happy. It’s more that if you want to do something, you can go for it. You may or may not succeed, but you have the possibility of fulfilling your ambition. Someone might share your ambition and you might end up fighting them. At that point both you and your opponent are fighting for your ambition, which can essentially be your world. At that point you will either be the person who taken away a world or your world is taken away. When your world is at stake, you will do anything it takes to keep it safe, even if it means taking someone else’s world. Ambition can be brought too many things, even a fight for survival, so I guess it’s complicated. This is all I can think of off the top of my head. I can expand in the comments if you ask a question

It's interesting because (insert explanation)

Why should you care? It’s a big question… why does this matter, what do these things have to do with what I’m doing now? In my opinion it’s why everything that interests you is there in the first place. What we have now is an evolved version of past works. Why was the TV show Psych created, it’s a modern version of Sherlock Holmes. Doesn’t Avatar seem a lot like Pocahontas at times? It’s not just TV and movies, rap can be considered poetry. It adds up to me so I would say that it’s interesting to see our roots to understand why we are the way we are now. Past works have influenced so much that we have today. Think in terms of art, you don't just paint anything and say it's your style, you relate to a previous style such as abstract, or still life, or a portrait, we need these styles to determine what to make. For literary works it's the genre's that determine what your story is about, whether it's fiction, non-fiction, historical fiction, science fiction, biography, fantasy, etc. You didn't come up with that genre, but it led you to create something. Look at these video's between Frank Sinatra and Michael Buble, it's the same song but sung differently, it's almost a different creation. What we will do to continue from here on will be to keep going. We’re not going to stop evolving our tastes so that’s my idea on how to proceed, stay the course. Things are constantly changing, but that doesn't mean that we have to forget the works of the past, we need to keep them with us. We shouldn't forget what we once were. It's good to have a sense of self.
