Not sure if this is what you mean, but I 'switched' from an ML consultancy to entrepreneurship. I now build and market my own projects ([1], [2]) and try to gain enough ad revenue to replace my former salary.
Started 1.5 months ago, and enjoying every minute of it! No longer occupying my mind with corporate power dynamics saves a lot of cognitive bandwidth, but to my surprise it has been replaced. I thought I'd feel more 'free', but instead I now feel self-imposed pressure to make this one shot count. I know my runway is limited, so every day that didn't tangibly contribute to bottom-line growth feels wasted. I can rationalize it by reminding myself that I can always get a job and try again later, and that I should be spending most of my time on mid to long-term goals that have delayed effects. But that hardly changes how I _feel_. All in all, I'm really glad I made the jump, and I'm still super excited about what I do now.
