Adobe Illustrator and I Don't Get Along

I've had Adobe Illustrator for a while now, and I'm still really now sure what I'm doing with it. Maybe I'm just not cut out for graphic design type things, but I'd really like to know how to use it better than I already am. I know the pen tool is the holy grail of Illustrator. So far the only thing I've been able to do is trace one of my drawings with the pen tool.



Eh, I guess I could make a coloring book? My drawing was crappy to begin with so that doesn't help me very much :P
