You operate an assassin's guild. People come to you with targets and money, and you kill the targets to collect the money. Spend the money on various necessities of life: food, safehouses, third summer mansions, etc.
Of course, you don't do every mission you accept yourself. You could die that way, after all. Hire, train, cajole, and coerce assassins into your service to do the dirty work, balance the books, bribe the right people, and you might just find yourself at the top of a criminal empire.
