Is it really bad luck or good luck?

I know we’ve discussed karma before but have any of you ever run into someone who truly seems unlucky?
Is a lucky person, just a person who knows how to make lemonade out of lemons or is it their positive outlook that continues to surround them with people who will bless their lives?
I haven’t met a truly unlucky person who didn’t seem negative. So is it their negativity that brings about bad luck or are they simply negative because of their bad luck?
I guess its like asking who came first. The chicken or the egg?
Only in this case, negative behavior or unluckiness?
