Never spend money you haven't received. Don't even promise someone money based on a promise you have from someone else. If someone tells you: "Ezra, come to my office tomorrow at 9am and pick #30K"don't go out to buy items on credit based on this promise, with the hope that you will pay off your creditor when the promised money comes; it may not come as promised and this will leave you in problems with your creditors.

If you want to save, whenever you receive money, don’t start spending hoping that you’ll save what remains. Normally what remains is zero because as long as money to spend is available, the numerous things you can spend it on are also available. And things to spend on even incite their 'relatives' so that you spend even more than you had planned. When money to spend is not available, we naturally find a way of doing without it. That's why I've learnt to save with an INVESTMENT CLUB. Once I send money there I assume I no longer have it. Before you spend any money, put your savings aside then spend what is left after saving.
