Truly exceptional artists are often right-Brained.
Mathematicians are often left-brained.
In fact, most people are left-brained whether they are mathematicians or not.
Many artists are not in fact right-brained, because they are not particularly smart.
They need to master their left brain before they become right-brained.
Some other categories of artist such as musician and computer-aided design people may actually be left-brain dominant, or split between right and left.
Brain dominance is generally the opposite of your handedness.
Left-handed people tend to be at least a little bit exceptional.
Ambidextrous people at this moment in history tend to have larger or slightly more complex brains than average.
Right-brain people are exceptional when they are mathematicians and musicians.
That's my sense of it for now!
