Agassiz does recommend authors to eat fish, because the phosphorus in it makes brains. But I cannot help you to a decision about the amount you need to eat. Perhaps a couple of whales would be enough.
He said that man’s heart was the only bad heart in the animal kingdom; that man was the only animal capable of feeling malice, envy, vindictiveness, revengefulness, hatred, selfishness, the only animal that loves drunkenness, almost the only animal that could endure personal uncleanliness and a filthy habitation, the sole animal in whom was fully developed the base instinct called patriotism, the sole animal that robs, persecutes, oppresses and kills members of his own tribe, the sole animal that steals and enslaves the members of any tribe.
It is easy to make plans in this world; even a cat can do it; and when one is out in those remote oceans it is noticeable that a cat's plans and a man's are worth about the same. There is much the same shrinkage in both, in the matter of values.
Therein lies the defect of revenge: it's all in the anticipation; the thing itself is a pain, not a pleasure; at least the pain is the biggest end of it.
Of all the unchristian beverages that ever passed my lips, Turkish coffee is the worst. The cup is small, it is smeared with grounds; the coffee is black, thick, unsavory of smell, and execrable in taste. The bottom of the cup has a muddy sediment in it half an inch deep. This goes down your throat, and portions of it lodge by the way, and produce a tickling aggravation that keeps you barking and coughing for an hour.
I notice that you use plain, simple language, short words and brief sentences. That is the way to write English―it is the modern way and the best way. Stick to it; don't let fluff and flowers and verbosity creep in. When you catch an adjective, kill it. No, I don't mean utterly, but kill most of them―then the rest will be valuable. They weaken when they are close together. They give strength when they are wide apart. An adjective habit, or a wordy, diffuse, flowery habit, once fastened upon a person, is as hard to get rid of as any other vice.
