As intense as the desire to study and learn is the anguish experienced on those days when possible knowledge seems irrelevant, possibilities extremely limited, and the means of learning insufficient. And it seems that time only intensifies them, as death approaches and conclusions must be reached quickly. At the same time, the urgency and sense of lost time worsen, at a stage when one thought it could be appeased. There is no solution: one must let the fleeting nature of it all pass and make the most of the positive, stimulating, perhaps somewhat illusory impulse, but one that does not run out and always provides a reason to want to wake up.
