Intrapersonal Intelligence is the inner quality of individual that helps focus on the skills of concentrating deeply on life all by oneself. This is the basic quality of being a good thinker. Every individual has unique set of qualities with a certain combination of all nine intelligences. The people with the strong presence of this intelligence are sensitive to own emotion, motivation and mental conditions. They are keen critics by self-understanding. Persons with strong Intrapersonal Intelligence are good at understanding own life and thinking for life in future. They are eventually good at learning alone and keeping distance from social events.

Keeping Apart from social gathering
Reading own mind
