I think the FI part is still a part of the movement, but many years in the RE part of it has been more or less abandoned...
This is true with many of the heroes of the FIRE movement.... They spend their days working on projects, writing websites, doing interviews, appearing in media. In addition to renting out and repairing houses, and numerous side-hustles.... I hate to say this, but to me, that's not the definition of retirement. However, these people are FI, which is wonderful and it affords them the opportunity to do what they want, when they want to. I'm happy for them.
For me, it is easy to identify every single dollar ever spent could be better put to use investing. I get that. I also know that at least for me, I need to enjoy parts of my life. I don't want to wait for retirement to be able to do at least some of the things I would like to. It's not a guarantee I'll make it there.
Which is why Pete so emphatically emphasizes that frugality is NOT the same as being cheap. If you feel deprived, you are doing it wrong.
I started my frugality journey when I went from being a broke student through my entire 20s to being a high income medical professional in my 30s. I started inflating my lifestyle through indulgent spending because, well, that's what you do, and I found it pointless and hollow.
Since I've embraced the concept that frugality *is* the way to being more happy and healthy, my life has become much
more fun and interesting.
It's not about spending less, it's about pushing your limits, your creativity, your understanding of what's possible, what options you have, and what you actually need to be happy.
The default solution to any problem is always to try and spend it away, but paradoxically, this often creates more problems.
For me, the exercise of thoroughly examining an issue and trying to creatively solve it without just throwing money at it means that I am just more thorough in my understanding of my own needs and the options available for meeting them.
By making myself look for a less spendy solution, I almost always find options that I never would have even thought of before.
Choosing to always at least try to find more frugal options has opened more doors for me than I ever thought imaginable. Frugality has never limited my life, it's radically expanded it.
Sometimes spending is the best way to meet a need, sometimes spending A LOT is the best way to meet a need, but the mindset of frugality isn't not to spend, it's to be diligent, thoughtful, and creative before jumping to spending, because there very well could be a superior option out there.
