One of my favorite Argentine poets, the great educator Almafuerte (1854-1917) wrote: "To the weak, difficulty is a closed door. To the strong, however, it is a door waiting to be opened." Difficulties impede the progress of those who are weak. For the strong, however, they are an opportunity to open wide the doors to a bright future. Everything is determined by our attitude, by our resolve. Our heart is what matters most.
