Friday the 13th is only bad luck if you choose it to be.
How do you handle superstitions?
I like the definition:
“A superstition is only a superstition, when it is not a superstition.”
In other words, if you can acknowledge that the belief has little or no ground in reality, then it is not a superstition, it is only when you believe it to be a truth (when in reality it isn’t) that it is a superstition.
And I acknowledge all the truth in what Bhatta says, confidence is most important in performance. How we come by that confidence is in one sense irrelevant – it is the confidence that works. So belief does improve performance in this sense.
