I come at it from a totally different direction.
My best life is frugal, so it's pretty self perpetuating. In fact all of my healthy habits are self perpetuating when I'm in a great place in my life: I eat well, exercise, sleep well, stay in touch with friends and family, and don't feel any urge to spend and own more for the sake of spending and owning more. When life is good, it's good.
So instead I register a consumerist urge as a signal to check if something is off in my life. It's a warning sign that there's some lack of balance and that I'm trying to meet and unmet need through spending.
Early on though, it wasn't so automatic. I found listening to ChooseFI podcasts when I cooked really helped me stay in the groove of the FI community mindset.
One thing I learned along the way is that you can't spend your way to your best life, and attempting to actually blocks your ability to build towards true happiness.
Living your best life takes work, it takes thoughtfulness, it takes effort to really reflect on what you need to be fulfilled, and creative thinking as to how to achieve it. Spending creates shortcuts, but in taking those shortcuts, you miss what matters.
Picture it this way, the path to happiness is a long, challenging hike through beautiful mountains. It's cheap or free to get access, it takes time and effort to get to the end point, and you may get lost along the way. Spending is more like jumping in your car, driving around the mountain, and then patting yourself on the back that you got to the other side faster.
Meanwhile, if you had hiked, you would have seen beautiful sights, your body would have exercised, your mental health would have benefited from being in nature, and you would end up on the other side of the mountain feeling peaceful, contended, proud, and satisfied with how you spent your time. Had you driven, you would miss out on the entire point of going to the mountain.
Spending short circuits your process of figuring out what you really need to thrive, it's a shortcut that gives you an artificial hit of satisfaction, and distracts you from your needs as opposed to actually meeting them.
So whenever you feel a spendy urge, take it as a signal that you have some kind of important unmet need, and the challenge is to get to know yourself well enough to understand what work is *actually* needed to meet that need, not just what purchase will quiet it down for a little while.
Your best life isn't found on the other end of a credit card transaction.
