Several years ago, before I had decluttered my stuff and organized my space, I had quite the embarrassing morning. I was working in a school at the time, about a half hour away from where I lived, and as I was trying to get out the door, I realized that I couldn't find my keys to save my life.
Until that morning, it was normal for me to shuffle around for 5-7 minutes longer than I thought I'd need, gathering all of my stuff as I headed out the door. My keys were always floating around somewhere, and I'd have to look around to find them, and most days I did.
That morning, however, I turned the house upside down looking for these keys for about 15 minutes before I realized that I needed to call the school and let them know I was going to be late. It must have been 45 minutes before I finally found my keys, and the experience taught me a life lesson: designate one spot for your keys.
Many people need their keys to leave the house and get to work. Other things can, and do, get left behind if it takes too long to find them.
