Friday the Thirteenth is a fitting time to remind ourselves that there's no evidence risks and probabilities in the external universe the brute, physical facts of reality change in response to human attitudes. Your optimism or pessimism may alter your own behavior, but it doesn't change the odds of you winning the lottery, getting hit by a meteor, or having your picnic rained upon (any more than the number thirteen does). It will rain or it will not rain, and the odds are in no way tied to whether you remembered your umbrella, despite the common belief in "fate."
