Idleness, inattention, confusion of the intellect, restlessness, gathering for killing time, haughtiness, pride, and covetousness,—these seven constitute, it is said, the faults of students in the pursuit of learning. How can they that desire pleasure have knowledge? Students, again, engaged in the pursuit of learning, cannot have pleasure. Votaries of pleasure must give up knowledge, and votaries of knowledge must give up pleasure. Fire is never gratified with fuel (but can consume any measure thereof).

In plain words: The faults of students are laziness, not paying attention, confusion, restlessness, hanging out to waste time, arrogance, pride, and greed. You cannot chase pleasure and learning at the same time; you must choose. Desire is like fire, which is never satisfied no matter how much fuel you give it.
