Technical writing! Are you an engineer? Do you love writing? Want to work in an environment that is far less stressful, but just as intellectually stimulating? You get to write neat articles, create helpful documentation. You are the first one to play with nifty features. Heck, keep writing small features if you want, or internal tools. You can have a big influence on inter-team communication.
It is the best choice I have ever made. I get to make great money, polish my writing and engineering craft, and day dream about my future fictions. In another 10 years, perhaps I shall pivot to fantasy. If not, I can point to dozens and dozens of popular, educational articles which people have enjoyed. And that will be enough for me.
