Do not go far.
And above all, know your limits!
لا تبتعدوا كثيراً. وفوق كلّ شيء، يجب
!عليك معرفة حدودك
Geht nicht zu weit weg und übertreibt es nicht!
Non andare troppo lontano
 e, soprattutto, sii conscio dei tuoi limiti!
Não vão longe. E acima de tudo,
saibam seus limites!
Далеко не уходишь. 
Помни, что во всём должна быть мера!
