Pyramid of Success 

Friendship 

"Comes from mutual esteem, respect and devotion. Like marriage it must not be taken for granted but requires a joint effort."

What I can guess from what this quote means, is that you cant be to naive that it will last you forever but the only way to maintain it is to truly respect one another, thought ideas and dreams. And as they say team work makes the dream work because once you paired up with somebody you cant be unbeatable and the fun never ends so you can never lose on a battle, there inst a lot of things to say about friend ship but the only way I can really explain what it means is to experience it first handed.
