In one sentence, describe what the following article is about: It's important to find the right envelope for your letter. If you choose an envelope of very light construction, for example, any heavy contents might break through the envelope while it's in transit. Take the following factors into consideration as you choose an envelope: The weight of the paper. The weight of the envelope should be appropriate for the weight of the paper and any other contents you may be mailing. If your letter is written on heavy cardstock, or you're including something else such as photos, choose a sturdy envelope that can handle the weight enclosed. The size of the envelope. The envelope's size should be appropriate for the size of the contents inside. Letters written on standard 8-by-11-inch paper are typically folded into thirds and mailed in business-size envelopes. Letters written on notecards may be mailed in smaller envelopes. The intent of the letter. If you're mailing a cover letter, you'll want to choose a professional-looking, business-size envelope. A personal note may be sent in a colorful, decorative envelope if you wish. The letter's destination. If you're mailing a letter overseas, you may want to use a sturdier envelope, since there is a greater chance it could get damaged along the way. Once you've chosen the envelope for your letter, place the letter inside and lick the edge of the envelope to moisten the glue, then press it shut to seal the letter. You can wet a sponge with a little water to moisten the envelope glue if you don't want to lick it. Place a small amount of clear tape along the edge of the seal if you are afraid the letter might open on its journey. Write the address of the recipient in the middle of the front of the envelope. Include the recipient's name, apartment or house number, street name, city, state or province, and zip or postal code. Use the nine- or eleven-digit zip code if you know it. You may use the two-letter postal code for the state if you wish. Use clear, printed, upper-case letters written in dark ink so that any postal employee will be able to read your writing quickly and accurately. If you are writing to someone outside your country, make sure you include the destination country's name in upper-case letters at the bottom of the address. Some people have their mail sent to a post office box rather than a street address. If this is the case for your recipient, write the correct post office box number followed by the city, state and country, if applicable. Write each part of the address on a different line to make it more legible. For example: SKYLER WHITE 2004 ROSETHORN COURT APT 4 ALBUQUERQUE NM 87041 In the top-left corner of the envelope, write your name and address. For ease of postal handling it is better to write your return address on the front of the envelope rather than the back. You may also use a printed return-address label. Including your address will ensure that the letter comes back to you if for some reason it doesn't make it to the recipient.
Summary: Choose an envelope. Enclose the letter and seal the envelope. Address the envelope. Write your return address.

Although you might have to read emails and reports for your job, not many people read regularly for fun. Reading requires you to be active and alert, so pick up a good book and get started. If you are trying to get in the habit of reading more often, start with a goal of reading one new book each month or every few weeks. Then, you can gradually increase your goal. Joining or starting a book club is a great way to get in the habit of reading more often. You will also boost your brain power and alertness by discussing the books with your book group. To train yourself to be more alert while having a good time, try playing games. Word searches, chess, crossword puzzles, and sudoku can help help you retain information and concentrate. Try setting up challenges that force your brain to be alert and on point. Here are a few simple ideas: Count items in your environment such as stop signs, coffee shops, or a type of tree. You can do this on your way to work or school, and while you are walking, driving, or riding a bike. Watch a digital clock that displays the seconds. Occasionally, the clock will skip a second. It's your job to identify when that happens. To increase the level of difficulty, add distractions to the mix by turning on a radio or television in the background. When you find yourself feeling foggy and less alert, try to force yourself out of your slump by thinking quickly. Here are a few easy ideas to start with: Increase your reading pace to feel more alert. Start a conversation about a stimulating topic such as politics. Work with classmates or colleagues to plan and brainstorm about a specific topic, and enjoy the surge of adrenaline. Learn about something new and interesting to increase your level of alertness. Practicing mindful meditation can help you improve your concentration and focus so you can become more alert.While there are many mindfulness meditation exercises you can do, here is a quick example that will help you feel more focused and aware: Find a quiet location free from as many distractions as possible. Then, pick a position where you are comfortable, but alert. Slowly take a deep breath in, paying attention to how your breath feels when it enters your body. Next, exhale slowly while concentrating on what it feels like when your breath leaves your body. It's normal to feel distracted, but try to focus only on your breathing. Noticing when your mind drifts and you become distracted is an important step in training yourself to be more alert. When this happens, don't feel bad. Instead, just calmly refocus on your breath.

Problem: Article: It is important to find and use your preferred stance to balance on a skateboard. The two main positions that skateboarders use are called regular and goofy. Try out both positions to see what feels the most natural to you. If your left foot is forward, or you are facing to the right you are in the position called "regular". If your right foot is forward, or you are facing to the left you are in the position called "goofy". Make sure that when you stand on the skateboard, your feet are positioned just behind the bolts. This is the best way to position your feet for good balance. Placing your feet in the middle of the board will not give you as much control and it also makes it easier to break your board. The bolts are what is securing your skateboard's wheels to the board, so your feet should be just behind the wheels on your board. Before you try to balance while riding your skateboard, start by balancing on your skateboard while it is standing still. The easiest way to keep your skateboard from moving around too much is to place it on some carpet or grass. Then, stand on your skateboard and work on your balance. You can also try placing an object in front of and behind the wheels on your skateboard to keep it from moving around too much. Try placing a block of wood on either side of your skateboard, or position the board between two cinder blocks. If you still find it difficult to stand on the board even when it is not moving, then you might try holding onto a railing or a wall to steady yourself and work up to standing on the board without holding onto anything.
Summary:
Determine your preferred stance. Place your feet just behind the bolts. Stand on your skateboard on carpet or grass.
