We have learned the simple truth, as Emerson said, that "The only way to have a friend is to be one."

Look at market fluctuations as your friend rather than your enemy; profit from folly rather than participate in it.

A friend should be a master at guessing and keeping still: you must not want to see everything.

Rejoicing in our joy, not suffering over our suffering, makes someone a friend.

One best book is equal to hundred good friends but one good friend is equal to a library

Where minds differ and opinions swerve, there is scant a friend in that company.
