Here it is, the proof that there are lucky people and unlucky people.

Let us divide any person's life into a series of events. Now, if for the sake of arguement, we divide each event into possible outcomes, one that is "lucky" and one that is "unlucky". And let us also say that each event has a 50-50 chance of being lucky or unlucky. Finally, let us deal with a sample of 1000 people, and assume a perfect theoretical distribution.

Amongst those 1000 people, 950, or 90% will be within two standard deviations of the mean. This means they will tend to have either slighty lucky or slightly unlucky tendencies. The other 5% on either side, however, will be unusually lucky or unlucky, and the luckiest and unluckiest person will be extraordinarily lucky.

Of course, this is a gross over-simplification. Accounting for the fact that the population is currently about 6 billions, and that the number of events that are determined by sheer chance are up for arguement, is left to the reader as an exercise.
