You don't want to have 
regrets, so don't slack off!
!لا تريدون أن تندموا لاحقًا، لذا لا تتخاذلوا
Strengt euch also an,
dass das keine Blamage wird!
No se descuiden, o fracasarán.
No bajéis la guardia, o fracasareis.
Ne relâchez jamais
votre attention
Di sicuro non vorrete avere rimpianti,
quindi non battete la fiacca!
Não façam corpo mole 
para não se arrependerem!
