“it is good to be solitary, for solitude is difficult; that something is difficult must be a reason the more for us to do it.

To love is good, too: love being difficult. For one human being to love another: that is perhaps the most difficult of all the tasks, the ultimate, the last test and proof, the work for which all other work is but preparation. For this reason young people, who are beginners at everything, cannot yet know love: they have to learn it. With their whole being, with all their forces, gathered close about their lonely, timid, upward-beating heart, they must learn to love.”
