Luck

I was thinking about "luck" this morning.

What is it, what does it mean, how does it work?
Are people born luckier than others?
Does it mean different things to different people.
Why do some people have all the luck in the world while others seemingly don't have any?
Are there lucky charms or lucky stars? If so where can I find them?
Do we take luck for granted?
Is this an all-purpose way of knowing we barely made it out of something?
Are luck and conscience related?

Any ideas?????
