And if you want to get better, 
just take the time and work at it.
وإذا أردت أن تصبح أفضل، فخذ الوقت وابذل جهدك
Wenn man besser werden möchte,
Y si quieren mejorar,
tómense el tiempo y esfuércense.
Y si queréis mejorar,
tomaos el tiempo y esforzaos.
Si on veut s’améliorer,
il faut du temps et de l’entraînement.
E, se vuoi migliorare,
prenditi del tempo e lavoraci su.
E se quer melhorar, apenas reserve
um tempo e trabalhe nisso.
А если хочешь стать лучше,
то потрать время на тренировки.
