Emotion

I found it easier to animate when:

1. You know what the objective of the character.
2. If you stuck with how your character should move. STOP thinking about "how". Start with what does the character feel at the moment...
3. Evoke the emotion! After all, animation is about showing your emotion, right?!

Do you know usually at work you get a task to animate flying objects, text, words, spheres, chair, brooms, crates or even just a cube. Don't worry! Don't just move it but have you ever thought of what these objects are actually thinking and what do they want to do?
(Don't call me crazy but I tend to do that, it makes animating much more fun!) Try it.
