Do you:
1) Believe? ["Never f--- with a winning streak"]
2) It's BS. ["I say 'f--- you, Jobu' --- I do it myself"]
3) "I Want To Believe"
They are definitely real.
Like others have said, when things are going good, stay with it . . . don't change anything.
This applies to other sports too.
For example, in basketball, when a player hits two 3-pointers on consecutive possessions, you should look to feed him the ball on the next trip down the court. If I were coach, I might even run a play for him to get him open.
This is very basic stuff.
Common sense . . . or, it should be.
