I need to stop hiding stuff from myself

I found my checkbook again. I lost it for the second time in a two week span, only to discover that just like last time, I had put it somewhere for safekeeping, then forgotten where I had put it. Last time, I found it in a plastic bag in my closet, this time it was underneath my keyboard. I found it accidentally while I was looking for a candy wrapper that I had dropped on my desk.
