I always try to be kind and not dole out facepunches right, left and centre, and I do think that everyone not in debt should get a free pass on one thing. My husband buys a stupid amount of books that he could totally get from the library. Mine used to be clothes but I think it might now be food/the garden (intertwined because I grow many vegetables, but we also buy fancypants cheeses etc). But we don't spend unnecessary amounts of money on everything. I pack lunches. I cycle again now. We buy rice and dried beans. We're not big on travel. Also, I bought a huge bag of topsoil and moved the whole damn lot through to the back myself. I grow things from seed mostly rather than plug plants. My garden is not an unending stream of leaking money, I just recognise it as a want, not a need. So we've picked what really makes us happy and spend on that, and are frugal everywhere else.
If blending things is your one extravagance and you don't have any debt and have an emergency fund, whatever. Buy the multiple-hundred-dollar blender. But that is your one extravagance. Don't come crying about how you NEED a pumped-up SUV for safeteeeey, or a huge wardrobe for wooooork, or takeaway for nutritiiiiiooon. No, you picked blending things. Go and cycle, thrift shop and soak your beans.
