Slamming Doors
Who doesn't hate the sound of a slamming door? That's why placing a small foam door bumper like the one above can be especially helpful. These things are pretty cheap online or in major retailers, and they help with protecting your doorways from the abuse over time.
Stripped Screws
Getting a stripped screw out of some old wood can be especially difficult, but there's a hack that solves this problem. Simply place a rubber band around the end of the screwdriver and use the rubber to get some grip on the stripped screw head.
