Today, January 20th, is so-called Blue Monday, apparently the most depressing day of the year. While experts do not believe in this day, they are still willing to give some tips on making sure you stay happy today.
"There is no scientific evidence for the existence of a day like Blue Monday," psychologist Jean-Pierre van de Ven of MIND Korrelatie said to Hart van Nederland. "The term was invented by a psychologist, commissioned by a travel agency that wanted to sell more sun vacations. It is purely a marketing term that spread like a virus."
