Even Superman needs the Justice League, where his strengths allow him to do things his teammates cannot. His friends use their strengths to help cover his own weaknesses. Not only do footy players need teammates to ensure they can take on the field, there are things a tall marking forward can do that a small crumber can’t and vice versa.
We all have strengths and weaknesses too, that impact our regular, daily lives, and require the support of others to help us conquer problems much too large for an individual.
