With the little info you are sharing, there are few things I could think of or for you to consider, in consideration of what is possible for you or not.
I put things in priority (to me is my work online, cause that what pays most and I dont have kid) So I try to make this the main importance and I NEVER answer the phone etc. I get back to people and other biz stuff once offline, or during breaks. BUT, I do work when most of the world sleep. So if your other business is in the day time, either find a way to return the calls once you have some while camming, or try camming when you know you can fully focus on that?
Also, are there some of the issues that are recurring ones that could be solved by training the lady to be more self-sufficient with various situations over time and not disturb you constantly for various things, whihc could maybe be avoided?
For the social time, TV and movies to relax, I do the same... but I try to see it as a "treat" that I deserve after have accomplish lots of other things, or when really drained or overly stressed. So I usually have my average of amount hours i do online, longer sometimes when busy, longer sometimes when dead, and other time its dead and decided to treat myself with less hours than usual, considering it may be a good time to chill some and rest some more for busier nigths. But I still have a minumum I pretty much never go below. I do really enjoy my down time then, knowing I deserved it and accomplished what I could prior to it.
I find the most efficient is to fully be dedicated to the "online time" to make it work and be regular and consistant (wherever that fits in your schedule) and then fully separate the personal time and other job time (sometimes the 2 jobs can overlap a bit, but can be tricky and thin out your focus and motivation. I find myself more productive when 100% in one thing then 100% in the other. Unless its all virtual, then I can bounce easier from one to the next, but again, that is tricky for most people in general)
