You don't need to fight with someone—
just be yourself.
Du konkurrierst mit niemandem.
Sei einfach du selbst.
No tienes que pelear… solo sé tú misma.
No tienes que pelear… solo sé tú misma.
Ce n’est pas une compétition,
reste simplement toi-même.
Non c'è bisogno di attaccare qualcuno,
cerca solo di essere te stessa.
Não precisa brigar com ninguém,
apenas seja você mesma.
Не нужно бессмысленных драк. 
Просто будь собой.
