"Whether we are happy or sad, whether we are healthy or sick, whether we are rich or poor depends on whether we use or misuse  our mind" - Dr. Pon Elango, Founder, Inner Universe.

Our brain is divided into two hemispheres and each side handles specific functions.
Left brain dominants excel in academics and research. They are judgmental, rigid and insensitive. They are perfectionists. They avoid taking risks. Right brain dominants excel in music, arts and crafts. They are creative, emotional and flexible. They are easy going. They are impulsive risk takers.

Though brain dominance is inborn, it is possible to develop the skills of the less dominant hemisphere and thereby perform at peak levels.
Knowing whether one is left dominant or right dominant can help in choosing the right profession, improving relationships with people, enhancing efficiency levels in various skills, solving problems with creative ideas, differentiating between calculated risks and reckless risks and developing the wisdom to know what can be changed and what can't be changed.
