Everytime I tell people about something great that happens to me before it happened, something bad will happen and cause the thing to not happen. For example just few days ago I was suppose to close a sale. The buyer told me he is coming down and I excitedly tell everyone about it and the next moment he decided that he is not ready for the purchase and pull out of the deal. This is not the first time this has happened and I wonder is it that we cant say anything to anyone before it happens or it will jinx? Is there anyway to counter this? I'm pretty sure that when I share my news I was super excited, so I'm on a good feeling frequency.

Have anyone here experienced this jinx feeling before?
