cero a la izquierda is a fantastic Spanish idiom that literally translates to "a zero on the left". Think about it: a zero in front of a number, like in '07', adds no value.
Figuratively, it means something or someone is worthless or completely insignificant. In the song, Shakira sings "el pasado es un cero a la izquierda" (the past is a zero on the left) to powerfully express that she's letting go of what's behind her and focusing only on the present and future. Learning idioms like this is a great way to sound more like a native speaker!
Cómo Dónde Y Cuándo is Shakira’s upbeat reminder that even when life feels like a grind, joy is just a towel, a swimsuit, and a good friend away. Over shimmering pop-rock guitars, she paints the picture of everyday stress and global problems—wilting flowers, city lies, trash-filled oceans—then flips the script with her trademark optimism: for every flower that dies, another is born. The chorus is a sun-soaked mantra that time flies when you are truly enjoying yourself, so forget the how, where, and when and focus on who you are with.
By the second verse, Shakira lets go of heavy baggage, declaring the past useless and the future the only thing worth remembering. The song’s pulse encourages listeners to live in the now, because today is all that exists. Ultimately, “Cómo Dónde Y Cuándo” is a feel-good invitation to trade complications for simple pleasures, criticize the world yet choose hope, and measure moments not by surroundings but by the people who share them with us.
