Oh ! how life is good
if you focus on the best
Come on try; if you do the life light up
The smilly face is a grace
Enough Carefree and Gloom
Tell me what costs the smile!..Light up for life
What is the gain to be disturbed from my brother
And saying that I don't need the brother
I walk alone saying this is my way
Ignoring that I had lost the way
Oh ! how life is good
if you focus on the best
Come on try; if you do the life light up
The smilly face is a gift
Enough Carefree and Gloom
Tell me what costs the smile!..Light up for life
The day hours elapse sweet and bitter
I will see all the sweetness not only the bitter
And I will make the days show me the pleasure
Which circulate inside me to see the univers joyful
Light up for life..it light up

Thank You Nejad!! what a good translation, finally I understand the song!
