I would say that there is (at 5 hours a day with a family) a fairly long learning curve to get to the point where you have learnt enough python/javascript then built something with it to prove your chops and then got a FT job.
You might be able to learn enough in 3-6 months to have someone take a chance on a 36 yearold junior programmer. But we are an ageist sexist industry.
So, if you are done with CSS / HTML but do not feel a burning need to program (you would have felt it by now), then yes I suggest you learn to program, always good, but instead try finding a decent programmer whom you enjoy working with (I would guess you have met some) - and then set up a side project of freelancing yourself and him/her to local businesses or SF startups.
Maybe start with local businesses, build up the working rapport. (Try charging retainers!)
If you just want a change, maybe running a side business that might one day become a FT operation is it.
