In Samoan, you would say "ou te fiafia i a oe" to mean "you're sweet" in English.
Tautala i lou mea manatua (Literal translation: Speak on your own thoughts/affairs)
The translation for "strength in family" in Samoan is "tautua ma le aiga" which emphasizes the idea of service and loyalty within the family.
Light as in "bright light" would be "moli" Pronounced Maw-lee. And light as in "light in weight: would be pronounced "mama" dragging the A's so it sounds like Maaamaaa.
This is my humble translation/interpretation of this beautiful phrase:
"Every day is a new beginning - O aso uma o se amataga fou.
Treat it that way - Tausi iai fa'apena.
Stay away from what might have been - Taumamao ma mafaufauga: 'o le mea sa tatau ona iai'
and look at what can be - ma taga'i i le: 'o le mea e mafai ona iai'.
Fa'amanuia le Atua (God bless)
Jessica is not a Samoan name so there's no translation for it in the Samoan language.
