While you can use any sort of coin, it's best to start with larger ones, such as a quarter, unless you're making a ring for smaller fingers. The coin doesn't need to be newit can be spare change you already have around the house. Make sure the coin isn't valuable before deciding to turn it into a ring. Look for a flat piece of heavy metal, a concrete floor, or any other solid, hard surface. This will be your base for hammering, and you'll hold the coin on top of the hard surface. Choose a surface that won't be damaged by a hammer. A bench vise is another option for a flat, hard surface. Hold the coin using one hand so that it's sitting up straight with a sliver of an edge touching the hard surface. Use a hammer to gently hit the edges of the coin, rotating the coin slowly as you hammer so that all of the sides are hit evenly. Continue hammering until the coin reaches the thickness of a ring. Make sure your fingers aren't in the way of the hammer as it's hitting the top of the coin's edges. How thick you want your ring to be is entirely up to youroughly 0.5cm (0.20in) wide is good. Thicker rings will take longer to hammer, so be patient during this step. Avoid hitting the coin with a lot of force, as this could turn it into an oval or damage the overall form. Make sure the piece of wood is thick enough that the drill can go down into the wood without messing up the surface underneath. Place the coin in the center of the piece of wood, and either hold the coin with your fingers or use an adjustable wrench to keep the coin steady. If you're holding the coin, hold the very edges so that your fingers won't be in the way of the drill. Hold the coin steady as you drill the hole. Start with a smaller gauge and drill all the way through the coin. Switch the drill bit to a larger size, then drill through the metal again. Once you've drilled the hole, the coin should be left with roughly 0.5cm (0.20in) of coin thickness around the entire edge. If you have a sanding wheel that attaches to your drill, this is great for sanding out the rest of the coin to create a smooth ring. Hold the coin steady using your fingers or some other sort of clamp as you sand the inside of the ring until it thins out. A dremel tool with an attachable sanding wheel is also a good option. Continue sanding until the coin is the thickness you want your ring to be. Attach a polishing wheel to your drill or dremel, using a small amount of polishing compound to get the best shine. Run the polishing wheel along the inside and outside of the ring, smoothing out all of the edges so the ring is shiny and completed. To use polishing compound, dip a rag or polishing wheel into the container of polish, using a small amount to rub over the ring's surface.

If you have the time, sleeping for just 15-20 minutes can increase your alertness by leaps and bounds if you have a cup of coffee (or any other form of caffeine) right before you fall asleep. The caffeine will take about 20 minutes to begin working, so you shouldn't have any trouble falling asleep right away, and you'll wake up refreshed. Sleeping just 20 minutes helps activate the right hemisphere of the brain, which is responsible for processing and storing acquired information. Brains benefit greatly from schedules. If you go to bed and wake up at the same time every day, even the weekends, your brain know when it's time to sleep and fall into a pattern. Getting proper nutrition will also ensure that your body has the proper energy throughout the day without having to resort to naps for extra strength. How much should you sleep to ensure that you're properly rested? Adults need anywhere from 7-9 hours of sleep per night. If you are pregnant or older, you may need even more sleep, anywhere from 10-11 hours. Some recommend going to sleep with your curtains halfway open. The early morning sunlight will send signals to your body to slow production of melatonin and start production of adrenaline, making it easier to wake up. It sounds hard, but don't let your mind go into the "fuzzy stage." When your mind starts to go blank, think about something, whether it's a joke, a movie, or anything else to keep your mind working. Even thinking about something that makes you mad can be extremely helpful. Unless they're drinking, you typically don't see an angry person abruptly fall asleep. Make a call to a friend or a cousin or anyone who makes you laugh. A light conversation will definitely refresh your mind and you will be ready to start working before you know. Take a stroll while talking on the phone. It will keep you active. People tend to converse more animatedly when they walk and talk.
