Like everyone else said, keep drawing. Make flipbook animations and animations on the PC. Learn some 3D animation techniques and if you need animation for PC on the cheap, do some small GIF animations just as quick and fun exercises. You could volunteer your in-progress-talents for some of the aspiring Constructors if you wish. Just PRACTICE!
For learning 3D, get Blender. http://www.blender3d.org
Currently, the new version is being completely reworked. So have patience as the Blender team hammers out the bugs.
For a good 2D animation program, check out Pencil. http://www.pencil-animation.org/
It hasn't had an official update in a while, but the Sourceforge page is still active, even as of yesterday. I haven't used it that much because I am terrible animation-wise, although it is fun! Check it out, it's very promising!
This is a tiny and helpful tool. Quickly converts a string of frames to an AVI file.http://makeavi.sourceforge.net
Good luck with your animation career!
