David Hume, on why many academic philosophers are miserable

From The Epicurean:

But of all the fruitless attempts of art, no one is so ridiculous, as that which the severe philosophers have undertaken, the producing of an artificial happiness, and making us be pleased by rules of reason, and by reflection...

You pretend to make me happy by reason, and by rules of art. You must, then, create me anew by rules of art. For on my original frame and structure does my happiness depend. But you want power to effect this; and skill too, I am afraid: Nor can I entertain a less opinion of nature's wisdom than of yours. And let her conduct the machine, which she has so wisely framed. I find, that I should only spoil it by my tampering.

To what purpose should I pretend to regulate, refine, or invigorate any of those springs or principles, which nature has implanted in me? Is this the road by which I must reach happiness? But happiness implies ease, contentment, repose, and pleasure; not watchfulness, care, and fatigue.

Am I reading too much into this?
