Rule 8. You'll be tempted to break the chain when you get to a reasonable amount of money (e.g. £50,000). This temptation will be overwhelming the more money you make. So here is the most difficult rule of all: You're not allowed to spend one penny of the money (apart from as a stake) until you have one million pounds+ in the bank. Then it's all yours.
I have to tell you that most people remain poor for one major reason - lack of discipline. This indiscipline permeates their lives from top to bottom. Rule eight is the toughest of the lot. Do you have what it takes? You think so? Hmm, I wonder. Imagine you have £100,000 in the bank right now. Can't you think of a lot of 'stuff' you would want to run out and buy? Can you resist this temptation? We'll see...
Rule 8. Detail. None of the rules can be 'enforced', particularly this one. It's up to you what you do with the money. But if you spend it at any point during the process, then that's the end of the system for you. Don't bother trying to pick it up again, because it won't work. Seriously.
The only thing you could do would be to start from 1p again at some future date. This is the most difficult rule. People just can't keep their hands off the money.
The second it builds up to more than a few hundred, they 'dip' into it for some 'essential' junk and ruin everything. This is about self-will and determination. If you don't think you've got the guts to see it through, don't even start the system.
Don't forget rule 4. If you make too much money you are free, indeed you must, spend it and not carry it over. But don't use rule 4 as a get-out to rule 8!
