I was a full stack developer for 5 years and an SDET for the next 7 and quit. I hated it. I'm a corrections officer at a maximum security prison and actually like it. I was underpaid, underappreciated, racking up credit card debt just to survive while living paycheck to paycheck. I actually had to get a second job delivering pizza. The SDET work was frustrating, stressful, disorganized, and I had no support and awful terrible team leaders and pms. This was at a large company you've probably heard of. I felt like I was in prison, now I actually am and I'm so much happier. I have savings and retirement, great credit, tons of time off, and while certainly not appreciated, I wouldn't change a thing.

I'd love to give it a go again if I could make the same or more money, work for decent people on interesting projects, work remotely, and have the same job security. I don't think it's possible.
