An important key to happiness is in learning to see things from the right perspective.
Learn to view the dishes in the sink as evidence of your abundant food. The hamper full of laundry as proof that you have plenty of warm clothes. When your two-year-old throws a tantrum loud enough to tilt the earth on its axis, deal with it, sure. But also be happy that your child is healthy enough to scream like that.
It's all in how you look at it.
