The word animation is derived from a Latin word anima, meaning soul i.e. when life breathes into types. The painting of animation started with the cavemen who used to draw pictures on the rocks surfaces. Then who can forget Walt Disney for the creation of his cartoons mainly the Mickey Mouse! In the present sense it means linking the series of drawings and simulating their activities together. It is a rapid display of 2D or 3D pictures to create an illusion of motion. It is an art form in which inanimate objects are brought into life by sequencing the drawn pictures.
Animation is a creative thing and one needs to have creativity while handling it. It not being a mechanical subject needs lot of passion and imaginative skills. One should have flair for sketching/drawing. It needs long hours of continuous work with a whole lot of dedication. One should be good at visualizations, select of colors and acting too. Though this profession seems to be quite unglamorous, yet it is very exciting and unless one has the complete dedication and interest in it one should not enter this field.
