i think obviously you wouldn't want to skip out on an important family event or something for a single sitting, but if you're talking about giving up regular practice for the sake of anything, this would be unwise and unbeneficial to yourself and everyone around you. you will be happier, a better person, a better husband, a better father, etc if you practice regularly that is for sure. the unfortunate reality is, is that people who don't practice don't understand the importance of regular practice and aren't going to be interested in furthering your progress... the world is not set up to foster our spiritual needs, quite the opposite, so sometimes you have to put your foot down. that being said, i don't see any reason you shouldn't be able to wake up early to sit or to sit before you sleep every day baring some sort of illness or disability.
