What is creativity, well for the clue is in the name. Its to create. But what? Well anything relay, if your doing something and its enhancing your ability then it creative. To become good a something takes dedication but above al it take understanding. A person must understand what it is he is attempting to do, be it a painting a piece of music or even plans for construction of a building. To think of the kind of people who are creative many would say artist's. But it falls to many professions even sports men and women. A tennis player for example must be creative to be able to manipulate the ball across the court as to make it hard for his opponent to hit it back. I would imagine it would take a lot of repetitive ball hitting to tune your senses to being able to accurately hit and object to the spot you desire. Having an idea is just the beginning, if its not created, its not creative. The skill is learning the outlet of your thoughts and ideas that way your creativity can shine through.
Applying these skill in our line of work rely lends itself to our creativeness as the medium we use allows the feel and life of our ideas to shine through. Does an idea that's created in different mediums have the same creative thinking. I would say yes because its the idea that that's the main part of what your showing, as long as the finished piece of work represents what your original thought and idea was the n the creative process have been successful. Be it a painting or a 3d model the idea and creative thinking behind it is the main point. As long as it executed well.
What motivates us most to be creative. I think a lot of it is pure devotion and love to that interest. In my case its games but also the medium in witch I use makes me want to do more. Creating something in 3d or painting it the process itself entertains and interests me. Other gain that focus someone to be creative would be financial gain. Money is an important commodity to everyone and talent is a rare thing to be talented requires creativity not purely to be original but to have good strong ideas and opinions. If the creative outcome is something that most would find something they wouldn't dream of doing then people will pay well for your talents.
Its hard to imagine our world without creativity, nothing would have ever been invented or envisioned. Everything that we see around us had to be imagined and then created. The creativity of the idea in my mind, is the hardest to overcome, but the drive and passion make the long road ahead worth it.
