I find that in my own home, the things that have caused me the most stress have been when I'm engaged in something and I have to stop to do something else or when I walk into a messy family room and the children are lounging around in it as though they don't see the mess. These are just a couple of tickers that get me going. Next thing you know I'm frustrated, the children feel my frustration through the change in my countenance, and my home has changed from a place of peace to a place where strife begins to rise up in the behavior and attitudes of my children. The question I've had to ask myself is, "What is most important?"

I also expect that my children follow all instruction without complaining in tone, words, or body language. There is a time to work and a time to play. Work is a part of life and to complain about it is to not only complain against parental authority but also to complain against God. Therefore I expect my children to work cheerfully so that they can unwind and play as a reward for their effort. To achieve this, there is a consequence of additional work for whomever complains about an instruction or task. Some times that means they'll miss out on part of a movie or other family activity because they have extra work.
I've found that consistency with keeping my expectations reasonable, setting goals to achieve my expectations, and enforcing appropriate consequences have really helped to create a more peaceful home, and I'm certain that the character that results from these things is something that the children will be able to carry with them well into their future.
