We ought therefore not to accept readily chance acquaintances, or attach ourselves to them, nor ought we to make friends of those who seek after us, but rather we should seek after those who are worthy of friendship. For one should by no means take what can be easily taken. In fact we step over or thrust aside bramble and brier, which seize hold upon us, and make our way onward to the olive and the vine. Cf. Moralia, 709 E. Thus it is always an excellent thing not to make an intimate acquaintance of the man who is ready with his embraces, but rather, of our own motion, to embrace those of whom we approve as worthy of our attention and useful to us.
