Now the Apostle, under the inspiration of the Holy Spirit, says, "Knowledge inflates: but love edifies." The only correct inerpretation of this saying is that knowledge is valuable when charity informs it. Without charity, knowledge inflates; that is, it exalts man to an arrogance which is nothing but a kind of windy emptiness.
I have heard that whoever loves is in no condition old. I have heard that whenever the name of man is spoken, the doctrine of immortality is announced; it cleaves to his constitution. The mode of it baffles our wit, and no whisper comes to us from the other side. But the inference from the working of intellect, hiving knowledge, hiving skill,--at the end of life just ready to be born,--affirms the inspirations of affection and of the moral sentiment.
Respect your soul: don't keep repeating "I'm going to make it". Your soul already knows that, what it needs is to use the long journey to be able to grow, stretch along the horizon, touch the sky. An obsession does not help you at all to reach your objective, and even ends up taking the pleasure out of the climb. But pay attention: also, don't keep saying "it's harder than I thought", because that will make you lose your inner strength.
