Keys to happiness in 2019: Gratitude, free time, and social connections
Many Americans hope to meet their goals for self-improvement and overall happiness in 2019. Yale professor Laurie Santos started teaching the course "Psychology and the Good Life" last January. It quickly became the university's most popular course, both in-person and online. Santos will teach a new session of her free online course called "The Science of Well Being" just in time for the new year. Santos joins "CBS This Morning" to discuss her new course.
