You must be a person full of energy and enthusiasm. You should have atleast a basic knowledge of animation. One must realise that this is a career where you are learn continuously. So you have to be someone eager to learn whether you are 15 or 50. You must be a team player and be able to communicate your ideas clearly and effectively to others. Everyone in the field of animation is an artist.
But everyone here also needs to be a manager. Most importantly unlike fine arts, here you are using your skills to communicate to a specific audience. The end user therefore always has to be kept in mind. While most animators are good at drawing, with the advent of technology, it is no longer a necessity. What animators need to be is creative and so if you can communicate your ideas on a computer screen as against on paper then that's just as fine.
