I am also totally left brained. Great with words, love learning foreign languages (French, Japanese, Spanish), write well, read a lot. No problem remembering which is right and which is left, but positively cannot visualize stuff in my head. I can learn spatial stuff IF I can mediate verbally---i.e., write down the steps, or talk through them mentally. I had to write down the steps for putting my bike rack on the car, but once I had them memorized, no problem anymore.

I flunked high school geometry (passed on second try, possibly because my best friend Susie was no longer sharing my desk and we couldn't spend all our time talking about boys). Also flunked 8th grade home ec, because after putting the armhole facing on backwards for the THIRD time (on that ubiquitous and unwearable sewing project, the "shift" dress)---each time carefully and seriously analyzing how it should go on---I carefully folded up the unfinished shift and left it at the classroom door. Urg. There just aren't any outlets in my brain for visual-spatial plugs, so they knock around against the walls in there aimlessly and after a while retreat, slightly depressed and vaguely insulted, I think.
