This account presents the core of my memorial presented during my pre-viva examination for the Ph. D. With its publication, I aim at reflecting, together with the reader, upon determinant moments of my becoming a teacher. My memories and reflections reconstruct this trajectory, from my first school years up to the pre-viva. I present facts that contributed to my profile as a teacher, in my own life history althougs they cannot reflect all its complexity. I follow this track of sucesses avoiding dealing with ill sucesses, errors and consequent sufferings in an attempt to overcome the contradictions present in moments of decision making.
