Article: One of the things that can make the difference between true north and magnetic north so difficult for navigators is that the effect on compasses can change over time. This phenomenon is called declination — as the earth's magnetic field fluctuates, the number of degrees by which a compass will be "off" from true north will shift accordingly. Thus, to accurately adjust your compass to account for this effect, you'll need a recent declination value for your location. Luckily, the National Geophysical Data Center (NGDC) keeps up-to date records of global declination values. At the NGDC website, you can enter your current location to receive the most recent declination value available for your area. Some physical maps will also include declination values for the area displayed in the map. Topographical maps are the most likely to include this information, though it can be in other types of maps as well. If you're considering navigating by map and compass, consider checking your map's legend to see whether the map contains accurate declination data. Note, of course, that declination changes over time, so old maps can quickly become out of date. For the most accurate values, use the most recently-published map available. Once you know how "off" your compass is from true north, it's not hard to adjust for this discrepancy. Begin by finding magnetic north. Hold your compass flat and level in front of you. If your compass has a travel arrow (usually a skinny red arrow on the flat lower portion of the compass, point this forward. Watch the motion of the compass needle. When the needle stops moving, note the direction the needle points. This will be the north-south axis. Most modern compasses have a needle that is half red and half white. In this case, the red end of the needle is the north-pointing end. If you're navigating by compass, typically, at this point, you would adjust the compass's bezel to that the direction you're intending to travel is directly in front of you, aligned with the travel arrow. In this case, since we want to find north, we'll turn the bezel so that the "N" (and the wide arrow beneath it) is directly in front of us. Note that this magnetic north, not true north — we still need to adjust for declination. Turn your body until the compass's needle is lined up with the orienting arrow on the bezel (and, thus, the travel arrow as well). You are now facing toward magnetic north. To find true north, turn the bezel the same magnitude and direction as your declination value. Most compasses will have degree markers on the bezel to help you do this. Next, line up your needle and your orienting arrow by turning your body again. You should now be facing true north! For example, let's say that we originally obtained a declination value of 14o E for the area we're in. If we're facing towards magnetic north, we would turn our bezel 14o to the east (clockwise, in this case). Then, we would turn to the left (which is west) to line up the needle with the orienting arrow, leaving us facing at true north (14o west of magnetic north).
Question: What is a summary of what this article is about?
Find your local declination from the NGDC. Alternatively, find your declination from a map. Find magnetic north with your compass. Turn the orienting arrow so it points ahead of you. Adjust for declination.

Problem: Article: In order to become a better player, you need to learn to play from all the positions. From the net to the back line, you need to get experience all over the court, regardless of your height and your skill set. Even if you're particularly good at one position, play from all over. Have good sportsmanship. Go after every ball, even if you don't think that you can get it. Go for every ball like it's your last hit, giving it your all each and every time you're on the court. If you're in it 110%, everyone else will feel the pressure, too. Soon enough, your entire team will be firing on all cylinders. The game of volleyball relies on good communication and the best team on the court is usually the team talking the most. Call "got" or "mine" really loud to avoid confusion between you and your teammates. Yell whether the ball is in or out. If you see a tip coming let your team know. Your whole squad will benefit from just one person talking. Good volleyball players know that they always need to get better. Learning to take constructive criticism and suggestions for improvement is an important part of improving your play, whether you're on a volleyball team or playing informally with friends. If someone, a coach or a teammate, makes a suggestion, listen openly and try to integrate new ideas into your practice routine. Make it a goal to get better. If you hit a ball out or shank a pass, try to stay positive. Just move on and focus on the next serve. Volleyball is a mental sport and by getting down, you will greatly impact your game in a negative way. Stay focused and intent on winning. Find the zone and stay there. When your teammates see you playing with intensity and poise, it'll rub off on everyone and improve the team as a group.  Be alert, even if you are winning with a 10-point lead, the game could easily turn around with a good server. Focus on seeing a game through till the end and not changing your focus until the job is done. Be a good sportsperson. Know that even if you don't win, you can always play another game and hit the ball twice as hard next time. Your teammates will appreciate your good attitude, regardless of your performance. High-fives, vocal encouragement, and positive vibes should always be coming from good players. Whether you're on the court or on the bench, always be cheering your team on and focused in with the game.
Summary: Practice from different positions. Hustle. Communicate with your teammates. Be coachable. Be a mentally tenacious player. Encourage your teammates.

Society is in a digital age, so if you want to attract attention, you need to be an active part of the digital world. You should have a website or blog, at the very least, as well as various social media accounts.  Sign up on every social network you can think of, but focus on the main ones including Facebook and Twitter. Linkedin is good for professional purposes, and Instagram can be a great way to share sample photographs. Regularly update your blog and other social media accounts. Make sure that you support and interact with other artists whose work you appreciate. Building good relationships with other photographers will help you more than hurt you. These people might be your competition, but they can inspire you, give you advice, and send clients your way if they lack the time or the specialized knowledge. Instead of seeking out a few individuals within the industry, look for online communities of photographers. If you only have one or two contacts within the industry, your connection gets cut off as soon as your contacts get too busy to keep in touch. Before someone hires you to photograph an event or a subject, that person will want proof that you are a good photographer. A portfolio will provide potential clients with the proof they need. A portfolio should consist mostly of photographs that represent the work you want to specialize in. For instance, if you want to specialize in family and personal portraits, your portfolio should not consist of pages upon pages of food photography. Aside from online advertisements, you should also consider using various forms of traditional print advertisement. At the very least, you should design and print up business cards that you can pass along to potential clients as you meet them. Aside from business cards, you can also place ads in newspapers or print up fliers. As with many small businesses, one of the best ways to get the word out is simply by asking the people you know to help you spread it. Be prepared to do a few sessions for free, too, just to build up experience and a reputation for fine work. Word of mouth goes much further if someone unrelated to you can praise your work to other potential clients.
