A very good suggestion given by the author. When we spend our time with children, for that time we forget about many stressed things of our life. Children have a very pure heart and they are really innocent, so it could be a reason to feel happy with them. I have a joint family and have five kids at my home only, they all are from different age groups 4 to 15 years. I always spend my time with them and I actually utilized this time, when I answer some of their questions, I really found that I am also learning too basic and moral values while advising them.
