Right Brain v. Left Brain

I've been pondering right-brained versus left-brain thinking in considering the optimal occupation for my particular sets of skills, inclinations and experiences.  I took this test online (http://www.intelliscript.net/test_area/questionnaire/questionnaire.cgi), partly for fun, partly to satisfy my curiosity.  I'm sure it's not an accurate tool -- it's an online test, after all -- but I thought it might give me a fair picture of my right/left tendencies.  Here are the results:

Left Brain Dominance:10(10)
Right Brain Dominance:11(11)

Apparently I'm pretty even between the two, skewing only slightly right.  No wonder I'm confused.
