This means that you should try to remain alert and not wander off into a daydream, mentally creating a to-do list, or even outlining what you will write your next research paper on. Forget everything except what you are listening to and watching devote all of your senses to the lecture. Being genuinely interested in the lecture subject will help you maintain the focus. If your mind starts to wander off-track, don't give in to the temptation. Focus your energy back on the lecture and start writing notes to help you concentrate. Avoid distracting yourself during the lecture by browsing around on your computer or smart phone. Devote your attention solely to the lecturer. If the lecturer makes points that you disagree with or find are worth further consideration, place an asterisk or exclamation marks next to the point and single-words such as "nonsense," "unverified," "explore further." This creates a connection in your mind with the possible further research avenues for you after the lecture. Questioning the research is a great way to solidify the information in your mind and propel you on to further study of the topic. If you are allowed to record a lecture, use this to your advantage. It is a great way to have a backup in case you can't understand your notes later or forgot just exactly what was said during the lecture. Keep the recording device on the edge of your desk so that the sound won't be muffled, then use it later to refer back to the complete lecture. Remember that you should not record lectures unless you have been given express permission to do so by the person who will be speaking. You should also keep in mind that going back and listening to the entire lecture over again can be quite time consuming. It might be a better idea to focus your efforts on taking more effective notes. If you want to make sure that you understood what the lecture was about, ask some questions at the end of the lecture. Raise your hand and ask for clarification on any specific points you were unclear about. You may also want to consider talking to the speaker after class to further clarify some of the details.

One-sentence summary -- Stay focused. Decide if you agree with what is being said. Use a recording device. Ask questions.

Q: They are also called "sink caps," and are used on kitchen and bathroom counters. They are L-shaped, so they cover both the top and side of the counter edge. Some places sell even smaller ones made specifically for corners. If you are going to be using these near a sink, get the kind with a raised edge. This will keep the water from dripping onto the floor. Match the material to the rest of the tiles on the counter. You can use a matching color, or a different color. These tiles are narrow, with a rounded top, and come in smooth finish, textured, and molded finishes. They are a great way to trim a tiled shower wall or backsplash. Match the material to the rest of the tiles. Use a matching or a coordinating color. These may also be called "pencil liners." Rail moldings are thin, decorative tiles made from natural stone or porcelain. They are molded on 1 side, similar to crown moldings on a ceiling. Use them as a border between a tiled surface and a wall, or between 2 different types of tile. Match the rail molding to the surrounding ones, or use a contrasting one for a more unique finish. Some places sell rail moldings as "cap moldings" or "chair rails." You can use these even if the rest of your tiles are made from a different material. Use a coordinating color and texture to really make them stand out. You will need to grind the edges of natural stone tiles into a bullnose yourself. Glass tiles typically have a smooth, uncut edge and a sharp, cut edge. Orient the tiles so that the smooth edge is on the outside of your tiled project. This way, the rough, cut edges will be touching one another. They are also a great option if you can't find matching V-caps or bullnose tiles to finish the edges with. Separate the wood trim from the tiles with caulk that matches the grout. Use nails, screws, or plugs to secure the wood trim to the counter. You can use them on all sorts of tiled surfaces, including counters, showers, floors, walls, and stairs. They are a great way to transition between tiled and non tiled surfaces. Make sure that you coordinate the metal finish to the surrounding metals, however. For example, if your shower has a polished chrome showerhead, use polished chrome edging. Metal edges come in different shapes. Use L-shaped ones for a square finish, or rounded/bullnose ones for a curved finish. Metal edges come in different textures, such as smooth, speckled, and brushed.
A: Finish edges and corners on counters with V-cap tiles. Edge walls or counters with bar liners if you want to add texture. Use rail moldings to transition between different materials. Use natural stone as a rustic decorative trim. Edge tiled walls with glass tiles for an elegant look. Use a wooden trim if you want a more unique look. Edge tiles with metal trim for a contemporary finish.

Article: You will want to fix your safe between studs to allow it to be recessed inside your wall and thus less noticeable. Use a stud finder to locate the studs behind the wall by running the stud finder across your wall. The tool will have an indicator to show when it has found a stud. Stud finders can be purchased from your local hardware store. If you don't have a stud finder you can knock on the wall and listen for a hollow or solid sound. If the sound is hollow then the location is probably between studs; if it sounds solid then there is likely a stud in this location. Knock a nail into the wall. As you hammer you will be able to feel if you hit a stud by the way the nail goes into the wall. These holes will be covered once you have installed your wall safe. Use a pencil to mark the locations of the studs on the wall. This will help orient your lines when you cut out the section of the wall. After you've found a good safe and a place to install it between studs, you are ready to cut into your wall. Cut out a small square of space big enough for your hand to fit through. If you find wires you need to be extra careful to go around them or reroute them. If you find plumbing in the way you may need to find a new location. If the wall is clear, you are ready to cut out a space for your safe. If something is in the way and you are not confident in your ability to safely move or go around it, the best option is to find a new section of wall. Mark the four corners of your square hole using a pencil. Use a level to make level lines between the four corners. It is essential that the top and bottom are parallel with the ground while the sides are parallel with your studs. The hole should be close enough to a stud so that you can attach it to your safe later. Make sure to measure and level correctly so that you don't end up with an uneven or wrongly sized hole. Use your drywall saw to cut along the marked lines. Start with the bottom edge of the opening and then cut the sides. You should cut the top line last to make sure the piece does not fall out beforehand, creating an uneven line. Put your safe into the hole, remembering to keep it help up with your hand. The door is the heaviest part of the safe due to the locking mechanism so be careful to hold up the corner so that it doesn't fall out on you. Drill holes into the sides that match with the holes on the interior of your safe. Drill in each screw and then tighten them firmly. This is an important step that prevents burglars from simply cutting your safe out of the wall and walking away with the whole thing. Place the shelves inside the safe in their desired locations, making sure you line them up correctly. Some shelves will have cutouts to make space for the door locking mechanism and door hinges; make sure these cutouts are in the correct locations.
