Good question, and for me, it has enabled me to live more freely with less fear.
I am naturally an anxious person, looking too much to please. I had spent many years working and working to prove myself and constantly in fear that I was going to make a mistake and somehow ruin everything that I had built. And even since starting a tenure-track job, I worried that even after the security of getting tenure that I would then wind up stuck. Even though I like my job, I worried that I would wake up one day, hating it, but having to spend decades more working at it and hating it.
Now, I have the freedom of the math of it all. I know how much we need to live (very, very little) and I know that even if I did somehow lose my job, we could financially get by for a long time with just a part time job or two. And, I have confidence that we could soon piece together something else that would work just fine (even if not exactly what I had imagined). Losing a job would lead us down a different path, but I can more clearly see how many more paths there could be that we could make work. So, the fear of losing my job is not a threat. Also, about 10 years from now, I can be completely free if I want, getting rid of the fear of being stuck forever in a job I don't like.
Living a life not based on fear changes everything. I feel free to be more honest, to not hide my true self, to say no, to say yes, to ask for things I think are reasonable, to choose to let go of other things if I decide I'm not being reasonable, etc.
So, while I can't think of a direct way any large life choices have been impacted, I do believe that it silently impacts all of my day-to-day choices, which add up to build my life.
