This document discusses how a CV is like the roof of a house and should be built from the foundations up. It says: 1) Understanding your values, passions, and skills are the foundations that need to be laid before writing a CV, just as foundations are laid before building a house. 2) Identifying your career goals and project is like putting up the walls of the house, which support the roof. A CV without clear targets is aimless. 3) A well-built roof and CV that starts from strong foundations and has clear goals will protect you from career difficulties, just as a roof protects from weather. But a roof or CV built without foundations and goals risks collapsing.
