One of the best definitions of luck I have heard is that luck is the intersection between preparation and opportunity. Many opportunities will just pass you by if you don’t notice them or if you don’t have the knowledge or skills to do anything about them (which is where the preparation comes in).

Luck has been researched by Richard Wiseman, and it is apparently possible to increase your luck by following these steps.
