i think the whole phrase is “count your blessings, not your problems”
but the second part gets omitted.
so I suppose “be grateful for the good things”.
I don’t think I could say luck though because that’s in a realm of superstition to me.
i use the incantation “good luck” sometimes but I try to say “I hope it all works out” or a more firm “you’ll do great!” if needed. I think that’s the most accurate from me that I can give.
oh I trailed off there
