And when they are, your perspective changes. The things that were important, somehow don't seem so important any more. So, if they aren't important now, why were they important before the kids got sick?
We tend to prioritize our tasks relative to each other, but the bottom line is that something is either important or it's not. Look at the things you're involved in; look at the tasks that you have to do throughout your day. Then figure out if they are important based on your values, your life goals and your relationships. If they aren't important, stop doing them. I'm sure you have enough important things to do!
