The real lesson should be one from economics, combine time and money based upon their current relative marginal value.
When you have heaps of time, thats the exact moment when you should be using it to set yourself up for future earning and saving of money.
When you work long hours and make enough money, use that money to buy back some time.
And if you "work long hours, make few money", my condolences, but that also gives you an important insight into the value of doing the former if or when you can...(under the assumption that the work isn't effectively future investment)
The further up the scale you go the more tenuous the link between hours worked and income becomes. Sure, if you are a part time worker paid by the hour or on minimum wage then increasing your hours will work.
For most people here I would expect adding an extra hour to their week will have little impact. They would be better tightening their spending if they want to improve their financial position.
