S'éternise is a beautiful French reflexive verb meaning "to drag on forever" or "to last for a very long time," often longer than desired. It comes from the word éternel (eternal), which gives it a poetic and slightly dramatic quality.
In the song, Luiza sings, "Demain en demain s'éternise", which poetically captures the feeling of procrastination. It describes how putting things off until 'tomorrow' creates an endless cycle where the future never truly arrives, and the waiting just drags on.
Ever told yourself you'll start something tomorrow? French artist Luiza takes that idea and runs with it in her alternative track "Demain Demain." The song is built around one single, powerful word: Demain [Tomorrow]. She repeats it over and over, showing how we fill our future with promises. Tomorrow is when you'll find love ("Demain tu trouveras l'amour"), when life will smile at you ("Demain la vie te sourira"), and when your luck will finally turn. It sounds great, right? This future is a perfect "terre promise" [promised land].
But there's a catch. Luiza points out the problem with living for a day that never comes. This constant waiting for a perfect future means you never actually live in the present. She sings that "Demain fuit qui le poursuit" [Tomorrow flees from whoever pursues it] and, most importantly, "Demain décourage aujourd'hui" [Tomorrow discourages today]. By always focusing on what you'll do later, you lose the motivation to do anything now. It's a clever and catchy warning about the trap of procrastination.
