He couldn't believe his luck.
A esos niños los abandonaron a su suerte.
Those children were abandoned to their fate.
Un verdadero hombre hace su suerte.
A true man makes his luck.
You are not bound to their fate.
— El señor de los anillos: La comunidad del anillo (2001)
Feliz es el hombre que está contento con su suerte.
Happy is the man who is content with his lot.
