Now that the kingdom of science has access to tungsten, they can finish building the cell phone.
It's the complicated stuff that 
gets me fired up, anyway.
.أنا أتحمس عندما تكون الأمور معقّدة على أيّ حال
Die komplizierten Sachen
bringen mich erst richtig in Fahrt.
Me emociona cuando hay algo complicado.
Me emociona enfrentarme a un buen reto.
De toute façon,
plus c’est compliqué, plus ça m’excite.
Io sono sempre stimolato dalle cose difficili,
Eu me empolgo quando as coisas 
são complicadas mesmo.
Я сам люблю решать сложные задачки.
