The work of the educator is to give himself, to leave a mark and seeds of integral formation in the places where he goes through his professional life, from the different roles that life offers him and gives him the opportunity to participate. Together with all the people who build society and citizenship, the educator participates in this noble task of "Leaving the world better than he found it" (Baden Powel) and this has been the commitment of the authors who articulate and build this publication.
