Dr. Kay Redfield Jamison has spent her life’s work researching the supposed link of creativity and mood disorders. Inspiration is the generation of ideas that form the basis of creative works. People at higher risk of bipolar disorder report stronger experiences of inspiration than those who are at low risk. The students who were at high risk for bipolar disorder consistently scored high on inspiration judged to be coming from themselves. I read a book on motivation before, intrinsic motivation is much more stronger than extrinsic motivation.
