Think that is a trickey question. If it's a job of course you have to pay attention to it, but if it's not a major area of your life like a job, that supports your family, I think it's just something you can do in your spare time and still help out humanity.
For people like me I think it has to be in balance where you have to prioritize in the moment what is most important. At home of course my focus would be on my family and making sure there needs are being met, but outside of home on my job, I have to keep it separate, and leave it at work before I come home.
Even if writing things an a book on such matters at home, it would be only at times when my family is in bed, or doing their own activities that don't include me during their down time. I think you have to just find balance in all activities you like to do and believe in.
