In [the soul] one part naturally rules, and the other is subject, and the virtue of the ruler we maintain to be different from that of the subject; the one being the virtue of the rational, and the other of the irrational part. Now, it is obvious that the same principle applies generally, and therefore almost all things rule and are ruled according to nature.
The desire to serve the common good must without fail be a requisite of the soul, a necessity for personal happiness; if it issuesnot from there, but from theoretical or other considerations, it is not at all the same thing.
It's prudent to gain the whole world and lose your own soul. But don't forget that your soul sticks to you if you stick to it; but the world has a way of slipping through your fingers.
We must never stop dreaming. Dreams provide nourishment for the soul, just as a meal does for the body. Many times in our lives we see our dreams shattered and our desires frustrated, but we have to continue dreaming. If we don't, our soul dies, and agape cannot reach it.
