Pierre Et Jean by Guy de Maupassant

The doctor awoke next morning firmly resolved to make his fortune. Several times already he had come to the same determination without following up the reality. At the outset of all his trials of some new career the hopes of rapidly acquired riches kept up his efforts and confidence, till the first obstacle, the first check, threw him into a fresh path. Snug in bed between the warm sheets, he lay meditating. How many medical men had become wealthy in quite a short time! All that was needed was a little knowledge of the world; for in the course of his studies he had learnt to estimate the most famous physicians, and he judged them all to be asses. He was certainly as good as they, if not better. If by any means he could secure a practice among the wealth and fashion of Havre, he could easily make a hundred thousand francs a year. And he calculated with great exactitude what his certain profits must be.

He would go out in the mornings to visit his patients; at the very moderate average of ten a day, at twenty francs each, that would mount up to seventy-two thousand francs a year at least, or even seventy-five thousand; for ten patients was certainly below the mark. In the afternoon he would be at home to, say, another ten patients, at ten francs each -- thirty-six thousand francs. Here, then, in round numbers, was an income of twenty thousand francs. Old patients, or friends whom he would charge only ten francs for a visit, or see at home for five, would perhaps make a slight reduction on this sum total, but consultations with other physicians and various incidental fees would make up for that.
