Navy SEAL Admiral William H. McRaven:

It was a simple task — mundane at best. But every morning we were required to make our bed to perfection. It seemed a little ridiculous at the time, particularly in light of the fact that were aspiring to be real warriors, tough battle-hardened SEALs, but the wisdom of this simple act has been proven to me many times over.

If you make your bed every morning you will have accomplished the first task of the day. It will give you a small sense of pride, and it will encourage you to do another task and another and another. By the end of the day, that one task completed will have turned into many tasks completed. Making your bed will also reinforce the fact that little things in life matter. If you can’t do the little things right, you will never do the big things right.

And, if by chance you have a miserable day, you will come home to a bed that is made — that you made — and a made bed gives you encouragement that tomorrow will be better.

If you want to change the world, start off by making your bed.

James Clear:

For two and a half decades during her adult life, starting when she left for college and extending into her 40s, Lee never made her bed except for when her mother or guests dropped by the house.

At some point, she decided to give it another try and managed to make her bed four days in a row—a seemingly trivial feat. However, on the morning of that fourth day, when she finished making the bed, she also picked up a sock and folded a few clothes lying around the bedroom. Next, she found herself in the kitchen, pulling the dirty dishes out of the sink and loading them into the dishwasher, then reorganizing the Tupperware in a cupboard and placing an ornamental pig on the counter as a centerpiece.

She later explained, “My act of bed-making had set off a chain of small household tasks… I felt like a grown-up—a happy, legit grown-up with a made bed, a clean sink, one decluttered cupboard, and a pig on the counter. I felt like a woman who had miraculously pulled herself up from the energy-sucking Bermuda Triangle of Household Chaos.”

She was experiencing the Domino Effect.
