Como ser feliz
Se você não tem o que quer
Ou faz o que não gosta?

How can we be happy
If it's all about money in this world?

Como ser feliz
Vivendo com medo de morrer
Ao virar cada esquina?

How can we be happy
In a world where guns and bombs
Mean that you control the world?

You will try to find happiness all your life. Actually, happiness is something you'll never have, but you'll always have hope to find it one day. Hope is what keep you alive, isn't it? If you don't have it, what more can you do to keep believing that one day everything it's gonna be alright? Think about it, and keep believing!
