Don't step on the crack
Are you superstitious? If you step on a crack what do you break? How about being under a ladder? Or a mirror and if you crack that somehow?
Do you have a lucky trinket that goes in your pocket to help with an interview or winning the jackpot? How about a lucky clover?
Or even a horseshoe that is placed in the house above a passageway.
Its a belief that can’t be verified.
A hope that if you believe and hold tight to doing certain things all will be well in the end.
There is plenty of superstitions out there and there is plenty of luck without them.
