You shouldn't let what happened
 yesterday get you down.
.ينبغي ألا تدع ما حدث البارحة يحبطك
Du solltest dich nicht
wegen gestern fertigmachen.
No dejes que te afecte lo de ayer.
No dejes que te afecte lo de ayer.
Arrête de ressasser
ce qui s’est passé hier.
Non stare troppo a rimuginare 
su quel che è successo ieri.
Não deve deixar o que
ocorreu ontem te derrubar.
Не зацикливайся на том, что было вчера.
