For years I spent hours searching for my keys.
Searching for my purse.
Searching for the mail I just brought in.
For the mail I was supposed to take out.
Lost in my own house.
And the solution was so simple.
I put a swivel hook on my key ring. If the keys are not in the ignition, or in the door lock, they are hanging from the strap of my purse, so I don't have to dump out everything in my purse to find them. And they were always at the bottom of all the other vitally important junk in my purse.
Then I started putting my purse on a hook on the coat tree. Voila! Now I always know where my purse is! No more just setting it down wherever I happen to stop after I walk into the house, then searching all over the place because I can't remember where I set it down.
As for the mail....
well, nobody is perfect.
So get yourself a swivel hook for your key ring, and put a hook by the door to hang your purse on.
Works for me.
