Think this is good advice. All my life I've been overly frugal, and I can definitely say this has limited me in some ways. Always choosing the second-best item, choosing flight destination based on where it is cheapest to go, over where I actually want to go, and penny-pinching on small things just to save $10. Over the last few years, I've gradually changed from the FIRE mindset I used to have, and I am working hard to spend more on things that either make my quality of life better, save time, or simply because I want it. You can always make more money.
