3. Be More Economical

This particular point could apply to so many aspects of life but, essentially, the message it that you can save money by getting more use out of everyday items. If you wash clothes after only wearing them once or twice, get an extra day or two out of them to save money on water. If you plan on buying a plant pot, use an upturned plastic drinks bottle that you would otherwise throw away instead. Or even make two cups of tea using a single tea bag. Every little helps!
