If you have to go somewhere, and need to have something with you,

don’t put it by the door.

put it in the car instead.

I have walked past my take-with-you pile so many times. I’ve even stepped over it. Obviously this is if you are driving to your destination and the item isn’t perishable.

When you arrive at your destination, it is so much better to say, “Be right back, I left it in the car.” vs. “Ugh, I forgot it at home.”

*Grammar edit: This tip would work well for a book, not “…isn’t perishable, like a book”.
