some usefull trics for dailylife use

• To protect the spines of books -- assuming you still have any -- bookmark them by leaving them open and hanging them off the edge of a desk or table. Never place books open, face-down, on a flat surface.
• While waiting for a subway or train, look for the scuffed areas of the white or yellow line on the edge of the platform. This is where the doors are most likely to open.
• If your hair tends to tangle, use a plastic hairbrush in the shower to brush in conditioner.
• Spread less butter on toast, then eat the toast butter side down. (Depression-era tip for saving butter. Also works with sugar and other spreads.)
  • If a pen leaks in your pocket, soak the garment in milk to remove it. 
• Cut the front panel off of pretty Christmas cards and use them as a no-crush alternative to bows for gift packages you're going to ship or take on an airplane. Make sure you don't give the card back to the person who sent it, though.
• Use Japanese ceramic soup spoons for soup and cereal. They're less likely to spill. Some are flat-bottomed or notched so they won't slip into a bowl.
