If you can hold on to the desire 
to learn new things,
إن استطعت التّشبّث بالرّغبة
،في تعلّم أشياء جديدة
Solange du immer etwas Neues lernen willst,
Mientras quieras aprender algo nuevo
Si no pierdes las ganas de aprender,
Si tu entretiens
ta soif d’apprendre,
Finché si ha la volontà di imparare qualcosa
Se você se agarrar ao desejo
de aprender coisas novas,
Пока в тебе живо желание учиться,
