Life is just learning 
one thing after another.
.الحياة مجرّد تعلّم شيء ما تلو الآخر
Im Leben geht es nämlich darum,
immer Neues zu lernen.
La vida es un estudio constante.
La vida consiste en aprender sin parar.
La vita è un continuo studio.
A vida é aprender uma coisa após a outra.
Мы всю жизнь чему-то учимся.
