It is always about the money, otherwise nobody would charge for window cleaning.
As the question asked are you earning enough? Not how much are you earning.
Our first week 9 years ago was 3 houses at £3.50 each a grand total of £10.50 and that was enough then, it paid for the kids school dinners for couple of days.
It is not how much it is what is enough......my answer is when you can afford to give it away to help others..... ask yourself this, when was the last time you gave a homeless person money or a Big Issue seller more than the cost of the magazine or gave away good work etc etc
Yes you all better believe it
IT IS ALWAYS ABOUT THE MONEY.
