If you want to learn to animate, you have to have passion for it. It's not something that you can just get better at by telling yourself "well, I'll learn tomorrow" day after day. However, it's the most fun you'll ever have learning any skill.
There are resources abound for animation, a lot more than used to be available. I'm not talking about a 'Learn Flash CS4 for dummies' book. That will teach you nothing except how to use a tool that will be outdated in a few years. You can learn tools on your own just by messing around and asking a question here or there.
Books you're going to want to look at:
The Animator's Survival Kit by Richard Williams (If anything you MUST get this one. Check Scribd.com if you can't afford it)
The Illusion of Life by Frank Thomas and Ollie Johnston
Acting for Animators by Ed Hooks
Pencil to Pixels by Tony White
Stop Staring by Jason Osipa

On top of these I would watch your old VHS Disney collection. Also ZekeSpaceyLizard (spelling?) has some awesome cartoon lists in his newsposts that you should check out. The Iron Giant has some of the best acting I've seen.
And when you watch anything, whether it be 2D, 3D, live action, or real life, anytime you observe anything, watch how it moves. Think about the motion, the action. You're an animator and you need to view the world as such. You can do it if you put your nose to the grind! Good luck!
"Animation can explain whatever the mind of man can conceive. This facility makes it the most versatile and explicit means of communication yet devised for quick mass appreciation. "
