Each man, say they, has enough and to spare on his own hands; it is too bad to be involved in the cares of other people. The wisest course is to hold the reins of friendship as loose as possible; you can then tighten or slacken them at your will. For the first condition of a happy life is freedom from care, which no one's mind can enjoy if it has to travail, so to speak, for others besides itself.

Context

Well, some of them teach that we should avoid very close friendships, for fear that one man should have to endure the anxieties of several. Each man, say they, has enough and to spare on his own hands; it is too bad to be involved in the cares of other people. The wisest course is to hold the reins of friendship as loose as possible; you can then tighten or slacken them at your will. For the first condition of a happy life is freedom from care, which no one's mind can enjoy if it has to travail, so to speak, for others besides itself. Another sect, I am told, gives vent to opinions still less generous. I briefly touched on this subject just now. They affirm that friendships should be sought solely for the sake of the assistance they give, and not at all from motives of feeling and affection;” source
