Theory: Our belief in our ability to create our own luck exposes us to more good fortune (or at least allows us to see the good fortune amidst a sea of bad).

In an early 2000s study, Dr. Richard Wiseman found that lucky people came across "chance" opportunities, while the unlucky people seemed to miss them. Both groups had equal access to these opportunities, but the lucky group saw what the unlucky group tended to miss.

Our daily thoughts, behaviors, and actions serve to expand or contract our luck surface area, which in turn determines our experience as a lucky or unlucky person.

The Luck Razor: When choosing between two paths, always choose the path that has a larger luck surface area.
