Problem: Article: Select a pillow, rug, fabric, artwork or furniture that will "lead" the rest of your decorating decisions. It should be colorful so you have a full palate to work with, and should tie into the energy and mood you want to set.  Don't stop at colors--consider the pattern (geometric, organic) and texture of your lead piece and how to work those elements into the rest of the room. Your lead piece doesn't need to be something new. It could be something you already own, or a vintage or antique piece you find on craigslist. An often ignored but essential part of decorating is having the right lighting. Rely on natural light from windows, table and floor lamps, and try to avoid harsh overhead lighting.  Dorm rooms and rentals often have a single overhead light fixed to the ceiling. If you can, swap it out for something more attractive, like an inexpensive chandelier from Ikea (remember to save the original lighting to replace when you move), or soften the light by hanging scarf or covering it with a lampshade.  Remember the lighting will affect how the colors appear in your room. That beautiful shade of green you painted your walls may look like swamp water in bad lighting. Use mirrors and other reflective surfaces to create light sources. You can choose a brighter or more muted version of the color to emphasize different moods. Once you've selected a color, stick to complimentary or analogous colors (the ones opposite your color or right next to your color on a color wheel) to avoid clashing. You don't have to cram every square inch of your room full of pictures and furniture--your room will end up looking unfocused, busy, and cluttered.  Having a lot of space in a bedroom can make the overall mood more calm and serene.  If you have a large piece of artwork or something you want to stand out from the rest of the room, try surrounding it with negative space. It will draw attention to emphasize that particular piece. Sometimes a room can just feel "off," and chances are it has to do with balance. A balanced room means that you don't have all your heavy furniture on one side, or all your exciting fabrics and artwork clustered together across from an empty wall. It can take a while to get it right, but try moving things around so that the things that dominate the room are equally spread out.  Try walking through the room to make sure there aren't any obstacles and you can move freely into the next room, or to the table, couch, or bed.  If you are using prints, try mixing to bring balance to the room. If you use striped wallpaper, try adding in less structured, more organic details, like a pillow with a floral pattern.
Summary: Choose a "lead" piece for your room. Make lighting a priority and create at least three sources of light in the room. Paint your room a color selected from your lead piece. Don't be afraid of negative (empty) space. Consider the balance and flow of each room.

In one sentence, describe what the following article is about: While the general stopping power of a pistol is measurably low compared to almost any long gun, you want to make an informed choice to give you the best advantage.  Smaller calibers, such as .380, 9mm, etc, generally result in a higher bullet velocity, reduced recoil which allows for fast follow-up shots, higher capacity magazines (or smaller framed guns), and higher velocity bullets.     {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/f\/ff\/Choose-a-Firearm-for-Personal-or-Home-Defense-Step-4Bullet1.jpg\/v4-460px-Choose-a-Firearm-for-Personal-or-Home-Defense-Step-4Bullet1.jpg","bigUrl":"\/images\/thumb\/f\/ff\/Choose-a-Firearm-for-Personal-or-Home-Defense-Step-4Bullet1.jpg\/aid139610-v4-728px-Choose-a-Firearm-for-Personal-or-Home-Defense-Step-4Bullet1.jpg","smallWidth":460,"smallHeight":345,"bigWidth":"728","bigHeight":"546","licensing":"<div class=\"mw-parser-output\"><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"}  Large calibers, such as the venerable .45 feature slower bullets that have increased overall diameter, allowing for a wider initial wound channel (which gives you a slightly increased chance of hitting something vital). The heavier bullets and generally high muzzle energies increase recoil, resulting in slower follow-up shots and the larger diameter of the cartridges means lower capacity magazines.     {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/f\/f9\/Choose-a-Firearm-for-Personal-or-Home-Defense-Step-4Bullet2.jpg\/v4-460px-Choose-a-Firearm-for-Personal-or-Home-Defense-Step-4Bullet2.jpg","bigUrl":"\/images\/thumb\/f\/f9\/Choose-a-Firearm-for-Personal-or-Home-Defense-Step-4Bullet2.jpg\/aid139610-v4-728px-Choose-a-Firearm-for-Personal-or-Home-Defense-Step-4Bullet2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":"728","bigHeight":"546","licensing":"<div class=\"mw-parser-output\"><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"} Most U.S. self-defense experts consider .380 ACP (9 x 17 mm Browning Short) or 9mm as the minimum for adequate defense, while European Police believe that .32 ACP (7.65 x 17 mm Browning) as adequate. Making an informed decision about what caliber you will use requires experience.  Shoot many different calibers and choose the biggest caliber that you can comfortably shoot and make fast, accurate followup shots with. A semi-automatic .22 pistol or Ruger 10/22 carbine with a high-capacity magazine is easy to control when shooting fast and can be very effective at close range (most home-defense shots occur at less than 7 yards), and .22 ammunition is very cheap. Furthermore, a .22 won't penetrate as many walls, thus reducing property damage and risk to your neighbors if you miss. You'll want to be able to easily afford enough ammunition to keep up a regular practice routine.
Summary:
Caliber selection in pistols is a hot source of debate amongst tactics-minded handgun users. The most crucial factor in determining what caliber you will choose is how accurate and comfortable you are with any particular caliber. Don't completely disregard a .22 if your objective is home defense. When making your decision, also keep in mind the cost of ammunition!
