INPUT ARTICLE: Article: Everybody feels sad or disappointed at some point in his or her life. If you never knew what it felt like to be down, you would have no reference point to understand what it means to be happy. The important thing is to keep a balance in your life between the ups and downs, and not letting the downs spiral out of control. A major reason why people feel inadequate or dissatisfied with their own lives is because they constantly compare their own circumstances with those of people who seem to be better off. What's more, people tend to compare the low points of their own lives with the high points of other peoples' lives, without taking into account that even the most "fortunate" people deal with their own struggles behind closed doors. Rather than comparing your life to people who seem to be better off then you, take a moment to compare your life to people who are suffering from poverty and disease. This will help you notice how fortunate you are, and realize that perhaps a lot of your so-called "woes" are actually quite trivial in the grand scheme of things.

SUMMARY: Remember that feeling down is a natural part of life. Stop comparing your life to other peoples' lives.

INPUT ARTICLE: Article: Make sure to attend every class, lab or discussion, even if it is not required. If you skip a class, you may miss out on important information, which is something you cannot afford if you do not plan on studying much. For example, during class, your teacher may give hints about what material will be on the test. Attending optional labs or class discussions will allow you to get some one-on-one time with your teacher. Use this time to ask questions about class materials, tests and extra-credit opportunities. Compare your notes with one or two other students in the class who also pay attention, take good notes and ask questions. Discuss discrepancies in your notes and abstract topics to deepen your understanding of the course material. Discussing things out loud will help you create associations between your personal experiences and the course material. This will help you remember important ideas on exam day better. Whenever your teacher puts you and your classmates into groups to discuss topics, make sure to take advantage of this time to work out complex ideas. Additionally, when your teacher asks the class questions, try to answer them even if you are unsure of the answer. This way, you can test your knowledge to see what you think you know and what you actually know. Don't be afraid to ask questions that may seem "stupid" to you. More often than not, they are not stupid at all, and other people are wondering the same thing. Don't feel embarrassed by answering a question incorrectly. After all, this is how you learn, and your teacher will still appreciate the effort. Don't forget to introduce yourself to your teacher. Let your teacher know what you hope to learn from the class. Also ask your teacher about their teaching style. This will help you prepare for class and take better notes during class. Go to your teacher's office hours or speak with them after class. Use this time to clarify concepts and to ask for feedback on your notes, essays, or exams. Alternatively, meet and talk with the teaching assistant (TA) if you are uncomfortable with or intimidated by talking to your teacher.

SUMMARY: Go to every class. Discuss topics with your classmates. Participate in class discussions. Talk to your teacher.

INPUT ARTICLE: Article: First of all, this method is much easier than it sounds. Fill a plastic bucket with enough water to submerge your rusted object and mix one tablespoon of baking soda or washing soda per gallon of water. Use hot water, the warmer the water, the better. Mix well until it dissolves. The electrolysis process will take the rust from the object you want to clean and eventually attach itself to this metal. You want the sacrificial anode to be big enough so that half of it is submerged and the other half the half onto which you attach your positive terminal is above water. This is very important. A steel can works fine as your sacrificial anode, provided it is big enough to be partly sticking out of the water. Rebar is good too. Make sure the can anode is magnetic to avoid confusing it with aluminum. You do not want to use aluminum or stainless steel as your sacrificial anodes for electrolysis. Connect a negative terminal (black in color) from a battery charger to a rust-free section of your rust-covered object for a good connection. You may have to manually scrape away some rust to achieve this. Fully submerge the rusty object, taking care to keep as much as possible of the wire out of the water. Caution: Make sure this rusted object does not touch the anode to prevent an electrical short-circuit (a short). Next, you will need to connect a positive terminal (red in color) from the battery charger to the sacrificial metal. Remember not to submerge the sacrificial metal completely, or you'll risk eating away at the positive terminal, which you don't want to be eaten away. If the sacrificial metal is completely submerged, consider using another wire as a mediator/connection between it and the car battery charger lead to keep the charger terminal and connection dry. The electrolysis process will gradually start working away at the rust. Let it sit for 12-20 hours. Caution: If you ever want to check the status of your rusted object, be sure to turn off and unplug the battery charger first. You will see bubbles rise to the surface and muck gather at the surface. Both of these things are normal. When taken out, your rusted object should be rust-free, but still in need of some cleaning. Use a Scotch Brite pad to remove any sludge on the object and a bristle brush to clean those harder to reach spots.

SUMMARY: Set up an electrolyte solution. Use a different, sacrificial piece of steel as an anode. Connect a negative terminal. Connect a positive terminal. Plug in the car battery charger and turn it on. Unplug the car battery and remove the leads from your objects.

INPUT ARTICLE: Article: Look in the book that you received when you purchased your unit or pull up your unit's manual online. There should be a section discussing enclosures or possible obstructions. It should state the recommended distance between any structures and the unit. Not following these guidelines when installing an enclosure or other structure could negate your warranty. If the air can't circulate around your machine, then it will be less efficient and more costly to operate. Keep the foot of space around the unit open and free of any obstructions. Keep any plants that you've placed around the unit trimmed back. No matter which concealment method you choose, make sure to keep your unit accessible for any service professionals. Look for access panels on the sides or top of the machine and leave enough room for them to be opened, if necessary.

SUMMARY:
Check the manufacturer's recommendation for enclosures. Leave plenty of room for airflow. Maintain accessibility for maintenance.
