for while men in adversity need help, in prosperity they need people to live with and to make the objects of their beneficence; for they wish to do well by others.

Context

“but one cannot have with many people the friendship based on virtue and on the character of our friends themselves, and we must be content if we find even a few such. 11 Do we need friends more in good fortune or in bad? They are sought after in both; for while men in adversity need help, in prosperity they need people to live with and to make the objects of their beneficence; for they wish to do well by others. Friendship, then, is more necessary in bad fortune, and so it is useful friends that one wants in this case; but it is more noble in good fortune, and so we also seek for good men as our friends, since it is more desirable to confer benefits on these and to live with these.” source
