When can I start being an arrogant millionaire (I'm 13 now)?

As the only son of a multimillionaire solicitor, and one of only two grandsons of an enormously successful turf accountant, it is quite evident that I will never have to work. But, just say that I would like to walk into one of the vacant jobs left by a member of my family of elite English Americans (from Vermont), what would I have to do?
