Whether it's shot, break, or defending your opponent:
If you don't believe in the success of that action you will unconsciously behave in a way that leads to failure.
Believe in the success of whatever you are about to do.
You don't see into other people's minds.
And you never know.
The encouraging word costs you nothing and it may give your teammate the spark of support he craves.
Avoid platitudes and genuinly support your bros.
The more you say something the less value it has.
"I love you" is a very strong statement, but not in case you use it instead of "Great meal, thanks".
Respect the frequency of using specific words if you want them to be respected.
