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．
