Be organized in the first place so you do not lose anything. Always put your keys, the book you are currently reading, your eyeglasses, etc. in the same places.
Keep a neat home.
BUT if you lost something, it is in a place you do not usually put it.
Try the UP, UNDER, and DOWN search approach.
Sometimes we misplace things because we break a pattern and put them UP, on top of something like the refrigerator, a bookcase, etc.
Or, we put somethng on top of it, like a coat newspaper, etc. and it is UNDER something. Or it somehow slipped under a bed cushion, etc.
OR, we lay it DOWN - like on the floor.
So, look in NEW SPACES.
You can always try the prayer to St. Anthony, Patron Saint of Lost Items:
Dear St. Anthony, come around!
Something's lost that must be found!
You may then receive a bolt of spiritual grace that tells you where the lost item is located. Try it - it works!
Life experience losing and finding!
