While people often tend to think or claim they're thinking from their intellect, a lot of what we go by, such as in choosing a significant other or a job, is based exclusively on emotional feelings. It would be wiser to try to bring intellect into major decisions, weighing pros and cons and attempting to be less biased by our heart in some respects.
Everywhere we go we are being asked to make emotional choices. From advertising to politics, our emotions rather than our intellect are being appealed to. The music we listen to, the tv and movies we watch are for the most part meant to get an emotional rather than an intellectual response. Thus, we play out this emotional roller coaster in every aspect of what we do.
