Success always necessitates a degree of ruthlessness. Given the choice of friendship or success, I'd probably choose success.

One of the most beautiful qualities of true friendship is to understand and to be understood.

Peace, commerce and honest friendship with all nations entangling alliances with none.

A true friend is someone who is there for you when he'd rather be anywhere else.

There are no rules for friendship. It must be left to itself. We cannot force it any more than love.

Friendship at first sight, like love at first sight, is said to be the only truth.

There is some self-interest behind every friendship. There is no friendship without self-interests. This is a bitter truth.

It is only the great hearted who can be true friends. The mean and cowardly, Can never know what true friendship means.

Friendship is the shadow of the evening, which increases with the setting sun of life.

So long as the memory of certain beloved friends lives in my heart, I shall say that life is good.
