Saban Saulic - Koliko ti srece zelim

Hello

Could anyone translate this song??
I found the lyrics:

Koliko ti srece zelim
svi bih srecni bili
svi sto su je sreco moja
u zivotu snili

Refren 2x
Idi, idi sreco moja
ljubav nije dug
idi, idi nado moja
ostacu ti drug

Koliko ti sunca zelim
vecno biti sjalo
uvek bi te sreco moja
zrakom ogrijalo

I wish you that much happiness (*alternatively, or actualy primarily, 'sreca' means 'luck' in serbian, but I feel 'happiness' is the word here)
That everyone would be happy
Everyone that, my dear,
Dreamt it in life

Go, go, my happiness (*alternatively, 'leave, leave, ...')
Love is not a debt
Go, go, my hope
I'll stay your friend

I wish you that much sunshine
That it would shine forever (for you)
It would always, my dear,
Warm you with its ray

Hope you like it..

Thanks

I had guessed the meaning right
Love this song!
