Ask HN: Developer burnout – how to rediscover the passion, or new career?

I've been developing software for the last 15 years and I've stopped 3 months ago and just quit. It wasn't the job, it was one of the better companies I've worked for, the people were nice, the tech was cool and the money was great. Outside of work my life is pretty fulfilled, my first child was born last year, and although its been hard its also really awesome.

I've just lost the passion for developing software :(

I've taken 3 months off so far, but still can't bring myself to open up some code - I'm wondering now if I should think about changing career completely, what can an ex-developer retrain into?
