Mima Mirkovic's name is one that is most associated with volleyball. And rightfully so, as the sophomore continues to build a case as one of the best players in the Pac-12, leading Cal in multiple statistical categories this season. What may be surprising, though, is to see that the Irvine, Calif., native, is also co-leading a DeCal course on happiness. Mirkovic not only opens the doors to her classroom, but shares experiences with her students as they discuss principles of more positive living. Mirkovic explains how taking the course based on the book "The Happiness Advantage" affected her life and how she ended up in the professor's chair. Cal Athletics goes Inside the Classroom with Mima Mirkovic.
