If you create any type of corporate training collateral you ARE a creative professional. Graphic Designers, Motion Graphic designers, video producers, traditional artists, etc. all deal with customers regarding creative, design focused projects. We have a lot to learn from those that specialize in the areas in which we dabble and never truly master.
I would encourage you to listen to the Media Artist Secrets podcast for some excellent commentary, tips and tricks, on being a creative professional. You should also be familiar with Creativecow.net as a source of inspiration and education. They have fabulous tutorials for all creative apps.
