Adopted from the following great insight shared by Simon Sinek from his book The Infinite Game
In a finite game e.g. football there are fixed set of players , rules are fixed , duration is fixed.As a result of this “winning” , being the “best” are options.
In infinite games where duration in unknown , rules are not predefined , players are unknown it is of paramount importance to a player to keep playing with the goal of advancement of a “just cause”.
In such a game where being the “best” or “winning” does not matter , it is very important to know and pick a “worthy rival” from whom a thing or two can learnt for survival in the long run.
