As iron sharpens iron, so a friend sharpens a friend.

Real friendship, like real poetry, is extremely rare - and precious as a pearl.

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

Never have a companion that casts you in the shade.

Let us be grateful to people who make us happy, they are the charming gardeners who make our souls blossom.

Depth of friendship does not depend on length of acquaintance.

Without wearing any mask we are conscious of, we have a special face for each friend.

Never explain - your friends do not need it and your enemies will not believe you anyway.

Silences make the real conversations between friends. Not the saying but the never needing to say is what counts.

A true friend is one who overlooks your failures and tolerates your success!
