If the doors in your house squeak, you might find that annoying!  So you could use some WD - 40 if you have some, if you dont you can use a few drops of cooking oil.  It will do the same thing to stop the hinges from squeaking.

If you have a sliding door that stickes.  Clean the tracks with some soapy water or run a bar of soap over the tracks or use a few drops of oil.  Either one of these things will stop the sliding doors from sticking.

Got a sticker that you really cant get off no matter what you do!  Try what I use, A piece of clear packing tape.  Take the piece of tape and put it on the sticker and press it down and rub the tape so that it is really stuck to the sticker, so that when you pull up the tape the sticker comes with it!  Use another piece of tape if the whole sticker did not come off and keep doing the same thing until all of the sticker is off. 

Got some marks on your floors or painted walls that wont come off no matter how hard you try!  Try the Mr. Clean Magic Erasers,  They really work like Magic!

You know how sometimes when you put a chair or table together or when you buy something and they just do not sit right!  Well then just try what I do it will work every time.  Use a piece of cardboard or a piece of really thin wood to fix them, so they will stop wobbling.  The cardboard or the piece of thin wood even works to stop even a book-case or a wallunit from rocking.
