I've embarked on a year of 'mindful spending'. I don't like the sound of frugal living or living on the cheap, but 'mindful spending' sounds better.
Adapting Marie Kondo's method, I'm going to ask myself 'do I really need' it before I make a purchase. (Does it bring me joy would give the wrong answer as so many things I don't need would bring joy!). Hubby came across this book last week so it will be interesting to see how much we can save. I'm already putting what I save from curbing my takeaway coffee habit into the 'camera equipment fund'.
