Drawers: If you have trouble opening tight fitting drawers, rub soap or candle wax along the upper edges to lubricate them..

OK... Here's a bonus one:
Drilling:
1: To stop a drill from slipping when drilling a hole into metal or ceramic tiles, cover the mark with adhesive tape... Drill through it and then remove the tape..
2: When drilling into the ceiling, drill through the base of a plastic bottom from any container, perferably a transparent one to make your mark visable.. This will catch the chips and stop them from going into your eyes.
