Summarize the following:
High school is the time when you start discovering things about yourself. During the first two years of high school, begin understanding what your interests are, what your aspirations are, and what your future career plans might be. Engaging in your classes helps you in a variety of ways. You get more out of your classes by participating, and you build better relationships with your teachers, which can help you in many ways in the long run.  Stay awake in class and pay attention. Don't sleep in class or text your friends if you are bored. Sit in the middle of the room or towards the front. Sitting closer to the board and the teacher will help you focus and deter you from getting distracted by things like your cellphone, classmates, and letting your mind wander to other things. Don't worry about looking stupid in front of your class; raise your hand and ask the question. If you are struggling with something in class or from your homework, don't sit there confused.  Answer questions when your teacher asks them. Do not be afraid to give the wrong answer; no one is right all the time. Participate in the class discussion. Use the main ideas, key words, and ideas you discovered in your readings or the class lessons. Offer insight or ideas when the teacher opens the class to student input. Each school has a list of required classes that students must complete to graduate. This includes a certain number of classes of language arts, math, foreign languages, and even humanities. During your freshman year, find out what classes are required. Ask your teacher or guidance counselor for help on figuring out graduation requirements. Attendance is important. Every day you miss school, you are falling behind in the work in your classes. Regular attendance is essential for staying engaged in your classes.  Most schools have an attendance policy. If you miss too many days, you may negatively impact your grade in classes or your graduation eligibility. Do miss school if you are very sick, like running a fever, vomiting, or have other medical issues.  If you are arriving late to school because of lack of sleep, adjust your sleep schedule. A consistent sleep schedule will not only help your attendance, but also help you be more alert and engaged in class, and make it easier to learn.

summary: Know your strengths and weaknesses. Be involved in all your classes. Ask questions. Know the graduation requirements. Don't skip class.

Sore muscles are a part of everyone’s life. However, muscle weakness that gradually worsens over a few weeks to a month may be a sign of PM. The possibility of PM further increases if the muscle weakness is widespread and on both sides of your body.  PM most commonly occurs in the muscles of your shoulders, upper arms, hips, thighs, and neck. The muscles closest to your trunk will be affected the most. You might also experience pain, tenderness or swelling in these muscles. You will feel these symptoms, along with muscle weakness, equally on both sides of the body. You might blame your muscle weakness on overexertion or “getting old” at first, then start to notice that once normal tasks become more challenging. As PM symptoms progress, you may have trouble lifting things, placing items on upper shelves, walking up stairs, carrying items, getting up from a chair, brushing your hair, or even raising your head from your pillow in the morning. PM in your neck muscles can also make swallowing more difficult. Contact your doctor right away if you notice this symptom. PM is rare, but anyone can develop it at any time. It’s more likely to develop in females than males, and usually doesn’t occur in people under age 20. Most people are in their 30s to 50s when PM emerges.  PM isn’t passed down genetically, but your genes may influence your likelihood of developing the condition. Certain viruses like HIV might also be triggers, but the truth is that PM usually occurs without explanation. For some reason, your immune system starts attacking healthy muscle tissue. While viruses like HIV can be connected to PM, it is more likely to develop in people with other autoimmune conditions, such as lupus or rheumatoid arthritis. PM can, in some cases, impact the muscles in and around your heart and lungs. This can cause difficulty breathing, shortness of breath, fatigue, and chest tightness or pain. Contact your doctor right away if you notice these symptoms, or, if necessary, contact emergency services. These symptoms can be caused by numerous conditions other than PM, but you should seek medical care right away no matter the cause.

summary: Take note of muscle weakness that worsens over several weeks. Consider if everyday tasks have become more challenging. Take your likelihood of developing PM into account. Seek immediate attention if you develop lung or heart problems.

The process for cutting a pet door into a metal door is essentially exactly the same as that of a wooden door, except for the tools you'll need. It'll take a lot more power to cut through a steel security door, or some other kind of metal door. Because you'll need to get the right angle on it and be safe, it's better to remove the door and lay it out in a flat position. Remove the pins from each of the hinges in the door by removing the cap and gently tapping the pin out. Pull the door free and lay it out on two sawhorses placed a foot or two from the top and bottom of the door. Just as you would on a wooden door, use your level to place the template straight on the door wherever you want it to be placed. Tape it on and trace it using your marker, then remove the template and discard it. To get your cuts started, use a heavy-duty drill to start the holes at each corner of the template as before. With a metal door, it's a better idea to start with a small drill bit, about a quarter-inch or so, and make a pilot hole to open up a space for the larger half-inch hole. After you've gone around and drilled a pilot hole at each corner, put a larger drill bit in the drill and go back around to open up a half-inch diameter space. You'll need a heavy-duty saw to cut through the metal, as well as extreme caution. Make sure you've got a heavy blade in the saw and that you go slowly, so you don't snap the blade while you're making your outline cuts. Go just as you would through a wooden door, starting in the bottom left corner and working your way around from corner-hole to corner-hole. You'll probably need to hammer out the cut after you've run the saw around it. A few taps should do it, and the loose metal should fall out easily. After cutting through the metal, it's likely that the edges will be somewhat rough with burrs and little shards of metal. It's a good idea to use a file and clean up those edges to make sure the pet door fits in securely and safely, and to make sure you or the pet won't catch on any sharp metal pieces while you're working. File off especially large burrs to create a smooth edge. You don't need to be militant, just gently work off any large burrs you notice from your cuts with the saw. Don't go around so much that you make the hole bigger. After the hole has been made, installing the pet door will be exactly the same. Fix both sides into the hole, sandwiching them together and fixing them into place with screws. Hand-tighten them each, one at a time, then work your way back around the screws tightening them until the door is secure and doesn't jiggle in the space.
summary: Remove the door from the hinges and lay it out. Trace the template onto the door in the desired location. Cut holes with a heavy-duty drill motor. Use a commercial-grade cutting jigsaw. Clean up the edges with a file. Install the door as directed.
