If you inherited your father’s wild eyebrows and need a quick trim, brush your eyebrow hairs upward with a toothbrush, then trim them with a nail clipper. (Make sure you know what you’re doing, though. Get them trimmed by someone else once so you can see how it’s done.)
Windex kills ants.
Got some dinged-up wooden furniture? For the smaller dings, rub a walnut over 'em.
When you travel, you can roll up your ties and put them in your shoes to prevent them from getting wrinkled.
My two-butch household doesn’t have an iron. We take our clothes immediately out of the dryer and hang them up, but if we forget, we just put our clothes in the dryer with a wet towel for fast de-wrinkling.
Forget to squeegee for the last few months? Get soap scum off the shower door with a dryer sheet.
Use a magnet to find nails and studs in your wall.
Tired of trying to find the tiny "R" and "L" on your earbuds? Just color a little ring around the bottom of one of the buds with a Sharpie.

If you like making iced coffee at home but dislike your coffee getting watered down as the ice melts, make ice cubes using cooled coffee and save them in your freezer. Use those for your iced coffee instead.
Wash out an old sunscreen bottle (needs to be one with a wide opening) and use it to store your keys/wallet/phone at the beach or pool while you're in the water. Safer than putting 'em in your shoe!

Want to organize your dresser? Tiny bottles (e.g., from baby food or single-serve plum wine containers) make terrific containers for quarters, chapsticks, and collar stays.
Velcro is awesome for keeping things like remotes, phones, etc. in place so you won't lose them.
Another great organizer: wooden cigar boxes for pens, pencils, paper clips, ticket stubs, etc.
Most eggs are good even 1-3 weeks past their expiration dates. Want to know if an egg is still good? Submerge it in a bowl of water. If it floats, it’s rotten; if it sinks, it’s still good.
