What is creativity?
Creativity is starting with ideas and forming them into a piece of work or something unique that is your own design either 100% yours or something improved on someone else's design. Being creative is being able to form your own ideas and make your own plans that are not copied off of other people. Someone who is creative can work alone and form ideas and plans for something such as a song,a book, or a video without the input of other people. When someone is creative they can come up with something that has never been done before that is different from the normal style at the time.
If someone can create something new and original like the original creators of rap, jazz, or rock did it can start a new thing that is popular that other people will do. The original creators of rap were creative and now there are thousands of rappers because they created something so good that could last for decades and still be popular. Creativity can also be just improving on something. If a custom car builder puts a Ferrari engine in a 1932 Ford he is working off of other people two designs but he was creative because he had an idea that he could do it and he had the creativity to make it work.
Creativity is not just quitting on an idea that is not ready and moving on to something else. It is also not copying. When someone copies an idea and tries to pass it off as their idea they lack creativity. Creativity is something everyone can have if they just try and think and be original.
