Raise your hand if you've ever had shampoo explode in your luggage. Or if you've ever had a really unnecessary spat with your spouse about loading dirty dishes into a clean dishwasher. See? These things are totally universal problems that we all face. And that means, yes, somebody's already thought of the perfect solution.
Problem: Bobby pins everywhere.
Solution: This case from Lovely Indeed, made from a Tic Tac container.
Problem: Your family uses a billion cups.
Solution: Everyone gets one special cup that sticks to the fridge with magnets, like these from Made Everyday.
Problem: Socks keep losing their match.
Solution: Download this $6 printable file from Studio 120 on Etsy, put it in a frame near the laundry machines and hot glue clothespins to the bottom.
Problem: You keep putting dirty dishes in a clean dishwasher.
Solution: A magnet, like this one from BrightNest, that you can turn over when you unload or run the dishwasher.
Problem: You have too many products in the shower.
Solution: This shower hacks video from Alisha Marie shows how to use curtain clips to hang face scrub and other bottles from a tension rod (or the towel rod, with shower rings that open).
Problem: All your keys look alike.
Solution: Color-code them with nail polish like I Spy DIY did.
Problem: The window blinds are always dusty.
Solution: Make a custom tool like this one from One Crazy House with dish towels and a pair of kitchen tongs.

Solution: Unscrew the lid, cover the opening with plastic wrap and re-close the lid, just like Graceship did here. Great for packing or when you need to move with spillable bathroom and kitchen supplies.
Problem: You never know which cord is which on your power strip.
Solution: A bit of colorful tape and a good pen will fix that, as you can see here from The Chic Site.
Problem: Your cords keep sliding off the desk.
Solution: Clip binder clips to the edge of the desk, then fasten the cords inside the clip handles, like here from LifeHack.org.
Problem: Your cords keep sliding off the desk and you can never tell which is which.
Solution: One part binder clip, one part tape label, from Everyday Dishes.
