I wfh doing telephone market research, working on the phones. It's zero hours and as you'd expect, not highly paid. Plenty of work available for those who are good at it though, and the hours are incredibly flexible. I enjoy it, and tend to work 9-5 Mon to Fri. Finish work at 5, and then get on with what I really love - making art. If I want extra cash, I work an extra hour or two into the evening.
I have no kids, still rent rather than own my own place, don't drive, happy to live frugally and find joy walking in nature, the odd meal out, cooking, reading, the local swim baths, the odd movie at the cinema. The part of the UK where I live is one of the cheapest places to rent.
Life is simple, and care-free for me. Once my shift is done, I do not think about work. I wouldn't want it any other way. I've done jobs that have more responsibility, and I'm just not interested. Being mentally exhausted by 5pm is not for me, the corporate world is hideous (for me), and I want to have the energy to be creative until 1am! The mid 40's is on the horizon, and although my lifestyle isn't what many people would want, especially at this age, I wouldn't want it any other way.
There's many ways to live life, and I made peace with myself a long time ago about choosing a job that gives me very little stress, albeit less money, than a job where I was anxious and too busy to enjoy anything else. Whilst all my friends were busy climbing the career ladders, and I'm happy for them, it's not the path that's a right fit for all of us. This all ties into really loving my freedom and it's the same reason I chose not to have kids.
I don't feel like a failure. I feel happy.
