Definition of luck

Dear answer person, Finals coming up, wish me luck ok?  By the way, I want to know your definition of ‘luck’.  Thank you! [3593A]

Finals?!  Yikes!  I guess I’ve been on holiday all summer.

I’ve always liked the definition of luck offered by Seneca, who wrote, just before not very efficiently killing himself, that “Luck is what happens when preparation meets opportunity.”
