1. Enthusiasm
Enthusiasm is essential in any form of animation. One thing animator must be good at is gesture drawings. Necessary to good gesture drawings are acting, caricature, anatomy, body language, perspective etc.
Your mental and emotional processes are you.
Without motivation you would accomplish nothing, and without enthusiasm, motivation would atrophy before you could make a quick sketch. A good example would be that your mind is a projector - Whatever you choose to put into it is what will be seen on the screen.
"Enthusiasm is the mainspring of the mind which urges one to put knowledge into action"
Wally "Famous" Amos

The following list of (principles) are what should be found in all animation.

The purpose of studying and analysing a scene is to acquaint oneself with the possibilities in the use of the principles in animation. Above is 28 principles, although they may be more at first these will have to be consciously, then hopefully in time will become second nature. When emotions are lax, knowing these principles will enable the artists to animate his scene intellectually, logically and artistically as well as emotionally.
