Correções de Textos: Inside the bus

Everyday I need to take a bus to go to my job, but I can't never go sitting because the bus is always crowded.
Sometimes I arrived in my job very tired because have so much traffic on the way and I stand inside the bus with a very heavy backpack.
The thing is that I have no choice because when I'm going with my car I spend time in traffic too.
Definitely I'm curious about how the traffic will work in the world cup.

Desde já meu muito obrigado.
