During my career I've come back to clubs after the summer break to see one of my team-mates not really at it because he's been denied a move to a bigger club for whatever reason, and you can see in his body language that he doesn't want to be there and that kind of thing is massively disruptive and negative.
When you hear Beast Mode, you automatically go to my size, but I always say the strongest thing I own is not my chest, my legs, not my arms. It's my mind. It's that mindset that says: Look, you're not always going to succeed but don't take it as a loss, take it as a lesson. That's the mindset of Beast Mode.
