You undoubtedly have established a healthy rivalry in your arena. Even if the relationship isn’t so healthy your endurance will be your best tool to help you come out on top. There is a direct benefit to acknowledging your current rivals and conversely a possible mistake to ignore them and underestimate them.
Ideally you want to use those in your arena to motivate you and push you to another level of success through competition. Study their good moves and duplicate them while learning from their mistakes. Soon you will benefit from making observations and improve your judgment. The key is to keep fighting your way up the ranks. You will constantly rise and fall, but your consistency and determination will help you outlast your rivals.
