Context

“After the first unlucky venture in fashionable life which absorbed his capital, he threw himself into his work with the first earnest enthusiasm, which is frittered away so soon over the difficulties or in the by-paths of every life in Paris. The most luxurious and the very poorest lives are equally beset with temptations which nothing but the fierce energy of genius or the morose persistence of ambition can overcome. Lucien used to drop in at Flicoteaux's about half-past four, having remarked the advantages of an early arrival; the bill-of-fare was more varied, and there was still some chance of obtaining the dish of your choice.” source
