Man.
I won't exaggerate and say it's "The Best Feeling Ever" or "Utterly orgasmic"
but... it's nice when I hit a road block with my avatar in blender, and I somehow manage to avoid despair long enough to look into why it isn't working, and figure out how to make it work exactly like I want it to. Even learning new tools along the way.
I guess I can say I'm decent at learning through doing.
