History
Blue Life was first published in 1934 in the book Port Calls (Přístav Volá) by author Jaroslav Foglar - it is described as several rules / taska that we try to accomplish every day so that we can color one box in the calendar blue in order to fulfill them. The goal is to get as many blue boxes as possible. Originally these rules / taska were called My Better Life and the term Blue life was introduced in 1947.
Jaroslav Foglar explains the meaning of these conditions/rules in the words of the book hero Láda Vilemín, who describes them as follows: "I try to live as an aristocrat. True and correct aristocrats were people of rare and beautiful qualities. And I want to be such an aristocrat, but not of an inherited peerage that would have passed to me without my merit, but who deserved it by his life. So I created a new, exemplary Blue Life and I try to live with it to become a true nobleman. Not by title, but by his actions, his whole life."
