Unless you absolutely know what yer doin’, the easiest way to double your money is to fold it up and put it back in your pocket. There aren’t no shortcuts, no secrets that your new friend or brother in-law are gonna let you in on, no miracles on demand. There’s no gold in them hills and if there was somebody already found it by now. It takes work and plenty of it is hard, but that’s the way it is. I’ve seen friends lose thousands on a couple of spins of a wheel or throw of the dice, or on ‘sure things’ that turned out not to be so sure.
