Good Friends by your Side

I learned that the best defense to have is not a suit of pride, but rather to go into war with good friends by your side.

Flynn Carsen from The Librarians "And the Trial of the Triangle"

I think this quote is saying that you can go into a situation with an overload of confidence and bluster, but that won't necessarily end in your success. Sometimes the best tool to have is the people by your side who provide you with the most support.
