1. My definition of creativity is when you can take an idea or thought and make some sort of art or replication of the idea. Creativity is a way of showing who you are in your way of doing things both extravagant to make a point, or an every day task that may go unnoticed. 
2. Creativity is very important because I would say that creativity is the main foundation of imagination at least a main part of imagination and without creativity, there would be no uniqueness in the world or in its people. Without creativity there would be no design or structural differences. Everything and everyone would be much like the other and have no way of expressing ourselves in any way which also then reflects on the entire world and it's unique aspects all over.
3. Not only can I think of a single time when I was creative, but multiple. I am creative every day from the way I dress to the route I take when I am driving. I'm creative when I write this or other things in a way that is different from other students. I am creative when I talk and piece together sentences. I am also creative when I create art by drawing or playing music. I am creative in everything I do.
4. For myself, I can just stay true to who I am and expressing my differences through creativity rather than following common trends. For others, I would encourage them to be themselves and to use their imagination on a day to day basis.
5. I know several really creative people, from my girlfriend to a few of my friends. They are all very creative and artistic. They are very unique in the way they present themselves and how they make other people view them and the way they are. They may not act weird or out of the social norm, but they are never afraid to be themselves and throw out ideas rather than staying quiet and following everyone else. They all have strong personalities and you know that nothing will ever change them into something they don't want to be, which some people struggle with.
