Read it through once

I prefer commencing with the consideration of an effect. Keeping originality always in view—for he is false to himself who ventures to dispense with so obvious and so easily attainable a source of interest—I say to myself, in the first place, “Of the innumerable effects, or impressions, of which the heart, the intellect, or (more generally) the soul is susceptible, what one shall I, on the present occasion, select?” Having chosen a novel, first, and secondly a vivid effect, I consider whether it can be best wrought by incident or tone—whether by ordinary incidents and peculiar tone, or the converse, or by peculiarity both of incident and tone—afterward looking about me (or rather within) for such combinations of event, or tone, as shall best aid me in the construction of the effect.
