Question: If you cut that €1 bottle of drinking water from your daily routine, how much extra money do you have in the bank after 20 years?

Answer: €7300!

And people say it’s impossible to save up for a house deposit???

The art of saving is all about being aware of how the small things add up over time. And when it comes to taking care of this fragile earth, it’s exactly the same. When you do a tiny thing like switching to tap water, that’s also 7300 fewer plastic bottles that end up in the ocean.

This book shows you the effortless ways you can build up the kind of cash that will not only get you through pandemics or unemployment, but set you up for a richer life and a more comfortable retirement – whatever your age. At the same time, it shows you why these habits are sustainable, impactful and better for the planet.

This quick, simple read touches on many of the trends and issues that COVID-19 has brought into sharper focus than ever before:

· Sustainable living

· Sustainable homes

· Minimalism

· Food security

· Pollution

· Zero waste

· Retirement planning

· Budgeting

And if you’re thinking all of this sounds like a playbook for killjoys, rest assured that journalist author R.A. Dalkey has put his savings to use racing cars, travelling to over 75 countries and getting the hell out of office life at 40. Because calculated saving doesn’t mean you say goodbye to a good life. If you choose your battles (are you seriously going to miss that Evian?), then you can take your pick of indulgences.
