Better lucky than good?
Or lucky because you are good?
Or only good because you are lucky?
Do "lucky" people actually have a higher allocation of luck than others?
Do they use more of their luck?
Or do they use it on bigger, more noticeable things?
On your "unlucky" days, do you have less luck than usual?
Or are you not noticing when you are lucky, and simply focussing on the bad?
Is it possible that your share of luck has been given to somebody else for the day?
