Ask HN: Take low-stress job to learn web dev in free time?

I am currently teaching myself to be a full-stack web developer with the goal of developing my own apps and making it into a career eventually. I currently have a full-time job as a clinical programmer. It's boring and stressful but does have decent pay and benefits. I've just started applying to valet attendant jobs in my city so I can have a low-stress day job while I continue to learn how to hack in my own time. I've made some good progress in the past year and is starting to churn out some code for real projects. I feel that if only I had a less demanding job during the day I can be more productive in my self-learning.

Has anyone else done this sort of thing? How did it turn out? Any thoughts/advice?
