Women are the centre of the family. It's the woman who decides what's eaten in the house, when to have the kids vaccinated; everything that has to do with the children's health revolves around her.

The world is full of what seem like intractable problems. Often we let that paralyze us. Instead, let is spur you to action. There are some people in the world that we can't help, but there are so many more that we can. So when you see a mother and her children suffering in another part of the world, don't look away. Look right at them. Let them break your heart, then let your empathy and your talents help you make a difference in the lives of others.
