You stand out in the crowd only because you have these many, many carrying you on their shoulders.

The happy man in this life needs friends.

If you wish to win a man over to your ideas, first make him your friend.

Friendship (as the ancients saw) can be a school of virtue, but also (as they did not see) a school of vice. It is ambivalent. It makes good men better and bad men worse.

Every man rejoices twice when he has a partner in his joy. He who shares tears with us wipes them away. He divides them in two, and he who laughs with us makes the joy double.

Men have never been individually self-sufficient.

As iron sharpens iron, so one man sharpens another

The ideal man is his own best friend and takes delight in privacy.

Nature never sends a great man into the planet, without confiding the secret to another soul.

A man is known by the company he keeps.

It may be true that he travels farthest who travels alone, but the goal thus reached is not worth reaching.

The important thing is generally the "next step." We ought not to take it unless we are sure that it is advisable; but we should not hesitate to take it once we are sure; and we can safely join with others who also wish to take it, without bothering our heads overmuch as to any fantastic theories they may have concerning, say, the two hundredth step, which is not yet in sight.
