I think my favorite simple logo is the one for H&R Block. It's a freakin' block! How much simpler can you get than a green square?

One thing that might be an idea, if you do any computer graphics, is to try some self-limiting. Maybe try drawing something with an icon creation program. I only say this because creating your own icons is quite challenging for similar reasons. You want something that doesn't look like other icons, something personal. But you also have to worry about that icon being shrunk in the Quicklaunch bar, or the top-left corner of the window that opens, and it has to be just as recognizable when smaller (like yours on a business card).

I don't know, just a thought. I stink at making icons
