I make it a point to only spend my time 
on things that I care about.
أحرص بشدّة على قضاء وقتي
.في القيام بأشياء أهتمّ لها فقط
Ich mach aus Prinzip nichts,
worauf ich keinen Bock hab.
Me juré a mí misma
que solo lucharía por mis intereses.
Me juré a mí misma
que solo lucharía por mis intereses.
Je ne bosse que sur
des choses qui m’intéressent.
La mia politica
è fare solo cose che mi interessino.
Eu sempre só gasto meu tempo
com coisas que me interessam.
Я трачу время только на то,
что мне интересно.
