Have you ever considered which side of your brain you favour?
Each side of the brain influences humans in different and sometimes opposing ways. Left-side tends to be more logical, analytical, scientific; whereas the right-side influences our feelings, emotional, imagination. Humans tend to favour one side more than the other, and this may influence the type of career-path that you take.
Have a look at this test, and review the characteristics of each side of the brain (this is really cool).
Another way to test it, someone told me once, is that you form a telescope with your hands and hold it up to your eye. If you choose your left eye then you favour your right-side, if you your right eye then your left-side.
Below are some of the careers which are suited to 'left-brainers', and 'right-brainers'. Natuarlly we have a combination of both, and some are less favoured than others, and some strong in both, but this might give you an indication as to which careers you might be more suited to.
