Get ‘first flush’ barminess out of your system as fast as possible. You’re going to do it if you get rich. Yes, you are. You are going to buy a sodding great big house, then more houses abroad, then servants by any other name, then you are going to start misbehaving. Gambling. Credit-card abuse. Expensive clothes. Whores. Drugs. Drink. Fast cars. Private jets. Big parties. Interior designers. Gold taps. The lot. This probably can’t be avoided. But the sooner you can work through this ‘barmy’ phase, the better your health will stand up, and the sooner you will get your second wind.
