20．At the risk of sounding lazy，I'll just be honest：I used to hate making my bed．Why should I bother？I'm just going to get right back into it later，and no one except my immediate family will see it．
But something I read last week in Charles Duhigg's"The Power of Habit"changed my mind．According to Duhigg，making your bed every morning is connected with better productivity and sticking to a budget．It has also been suggested that making your bed promotes happiness．My interest was attracted．
According to Duhigg，making your bed is something called a keystone habit．Changing or forming keystone habits helps you develop other good habits．
I figured that I was the perfect test case for the Make Your Bed to Achieve Happiness Theory and that it was worth a try．So far I've made my bed for 10days in a row．And here's what I've noticed：Making my bed inspires my children to make their beds，clean their rooms and do the laundry and the dishes．
Karen Miller，author of"Hand Wash Cold"，explains："The state of your bed is the state of your head．"I think she is on to something．When I leave my bed in a heap （一堆），I leave the bedroom feeling defeated by my bed，my alarm clock，and my general sleepy mood．I'm reluctant to get the day started．
But when I look at my freshly made bed，I have to admit it：I smile a little．I feel just a bit more motivated．Productive，even．But sticking to a budget？That part is still up for debate．I just bought some beautiful pillows for my freshly made bed．I can't leave that beautiful bed half-dressed，can I？
