4) Strictly distinguish between expenditures and investments: it's very easy to put everything as cost or overhead: don't do this. Apply an easy rule: expenditure or cost is money thrown out of window - you can't expect any return money on it, while investment is desirable (of course, not every investment is desirable): this should bring you more money, more property able to make you more money - only questions you should carefully consider are whether you can/should afford such an investment at moment, how much you're going to get back, how fast and whether it is acceptable.

5) Keep your expenditures at minimum with no regard to how much money you have: expenditures are killing for everyone. It's useless to tell you stories about big fortunes lost by unwise costs. I'm sure you know many yourself from your neighbourhood.

6) Avoid loans, don't borrow if you don't know for sure you can repay. Never purchase anything on future incomes or promises.

Just a little example: if I have a notice that a payment is on its way to my account and I need money today for some reason (however, I can't see any reason like that :-) - never mind), I can borrow. But, if I think I will sell 1,000 books next week, I mustn't borrow.

7) You must always earn more than you spend. In case you don't earn more than you spend, then you must spend less. In other words, you must always be in green.

If you think that you must swap your car every six months even if you should borrow, then it may easily happen that you won't drive anything in a very short time.

I don't want to waste hours of your precious time by long essays on savings and wise advice. Just adopt one principle and whenever you want to do something with your money (- whether it's thousands or millions or just a couple of bucks), just think about it: take care of pennies and pounds will take care of themselves.
