I love the theory about four types of luck.

Blind luck: You're walking and find money on the ground.

Luck of activity: You go walking a lot, if there's money on the ground you're likely to walk by it.

Luck of optimism: You know you're lucky, so you're always looking for confirming evidence. If you walk by money you're likely to notice.

Luck of eccentricity: You don't walk along the same paths as other people. If there's money on the ground, you're likely going to be the first to walk by it.
