There are teachers who, despite all their challenges, who have those skills, get into those schools and are  able to engage an audience, and the administrator walks by and says, "Wow, he's so good, I wish all my teachers could be that good."
Hay profesores que, a pesar de todos sus retos,  tienen esas habilidades, entran en las escuelas y son  capaces de cautivar al público, y el director pasa  por allí y dice: "Caramba, es tan bueno, quisiera que todos  mis profesores fueran así de buenos".
