Scientifically Proven Ways to Be Happy Again

During the winter holidays (peek depression season), I took a free online course called The Science of Well-Being offered by Yale University. It was actually recommended in a HackerNews comment that I came across in a thread about different MOOC (Massive Online Open Courses) to take. Other than my obsession with self help porn, I took this course because I wanted to learn on how to be happy again with life.
