It's difficult to take a second job when you're already working 60 hours a week of course.
The other option is cutting back on what you spend and, obviously, that is easier to do the more you earn. I know, we reduced our income by 50% and we manage. We do without lots of things, but we have a roof over our heads and food to eat.
Swimming and dancing, whilst lovely, are hardly necessary. Organic and free range food is wonderful, but if you were really on the bones of your arse you'd manage a basics carrot, I'm sure.
We don't need half the shite we spend our money on. Can you imagine our parents and grandparents buying a new TV just because there was a newer model available? You made do with what you had and when it broke you had it fixed!
