Everybody do it, not only you, everytime that someone has a big luck with just wearing a t shirt or a pair of shoes are always going to use it as a "lucky stuff" to keep earning more money on the next session.

There is nothing new with this, a lot of people are exactly doing the same.

The same happens with the football players, everytime that there is an important match, they try to use the same sockets that they used on their lucky day, or their "lucky" shoes too.
