Certainly! Perhaps such rituals (private and incomprehensible to others) have with most people. For example, when I make yourself a mental installation (I practice the theory of positive thinking) does not use the word "no". For example, instead of "I don't want to be sick" I say " I want to be healthy." Another strange ritual I do all of my life I count everything. For example, buying vegetables, fruits, bringing logs of wood for the stove, I must have an odd number. I believe that it will bring good luck. Even when I drink water, I think made by pharynx. Only odd( 3,5,7,9...)!Ha ha. For some it's ridiculous, but I do it all the time!
