Aprumar means 'to straighten up' or 'to get oneself together'. It's a less common verb that carries a strong sense of self-improvement and resilience.
In the context of Tim Maia's song, the singer declares, "Vou me aprumar" (I'm going to get myself together). This word perfectly encapsulates the song's theme of overcoming heartbreak and making a conscious effort to move forward and be happy, making it both interesting and inspiring.
Tim Maia opens with a vow to himself: 'Vou lutar' [I'll fight], 'Vou vencer' [I'll win]. Under it sits a plain admission of heartbreak — 'Te esquecer' [I'll forget you] — but he turns it into a task rather than a wound, repeating 'Depende um pouco' [It depends a little], 'Do meu próprio esforço' [On my own effort] like a mantra through the whole song.
By the second verse there's already someone new: 'Uma linda menina' [A beautiful girl], 'Aqui do meu lado' [Here by my side]. And when he sings 'Não me interessa' [I don't care], 'Quem foi embora' [Who left], it reads less like real indifference and more like a man talking himself into moving on.
