Not only does having my bed made first thing in the morning force me to get up and get some work done, I can mentally pat myself on the back for accomplishing something that I needed to do that day. Though I'm not a big napper, one of my guilty indulgences is crawling into bed in the middle of the day and have a TV binge. Not anymore! I don't want to mess up my covers and then have to redo them all over again. Now if I want to watch a few episodes of whatever I may be into at the moment (and as of today it's Modern Family, just started and am in the second season. I love it), I do it at my desk. With all my books and homework staring at me. I don't binge anymore.
And finally, my favourite thing about having a well made bed: it feels so freaking good to slip into at night. I don't know, but there is something about smooth, tight sheets that is oh so satisfying after a long day. So long story short: make your bed every day. I have to keep this habit.
