Luck
Luck does not exist. Quoting Ron Swanson, luck is a concept invented by the weak to explain their failures.
There is, however, a cause for every effect, and an effect for every cause.
What is referred to as beginner’s luck is an invitation to continue the journey. I won my first-ever game of Go despite playing against a world champion doing his best.
The lottery is a tax on people who are bad at maths, and even more so on a supposedly lucky day: it is probabilistically unlikely to have multiple yuge unrelated events happen in a day. Altho I do suppose that one’s spiritual energy field reaching a certain frequency can make it more probable. Trust your gut.
