I would like to thank:
Nick Clarke, for always checking my work before publishing it.
To my kids, Pablo and Lucía, for their recommendations. They are my main source of inspiration and example to follow.
To all those teachers who believe in change, especially Pepa Botella and Loli Sánchez.
To my 1º Bachillerato students, some of whom I have taught since 2º ESO and thus have become an essential part of my professional development. They have always been willing to accept new challenges. This wouldn't be possible without their enthusiasm and love for the English language at all times.
