Ringworld (brought to you by Nivens and Pournelle) included a subplot where an alien race convinced humans to breed for luck. After 5 generations, they had a number of "successful" lucky people, people that could essentially warp reality in their favor.

(shrug) "Luck" is really just random chance. But if you work hard and are well prepared, you may be more likely to take advantage of "luck" when it happens.
