T-intersections are where two hallways intersect and there are two separate corners to clear, neither of which grants better cover than the other. You essentially have double the space to clear, and several blind-spots further down either side of the uncleared hallway. The reasons behind this will be explained in detail later. The number one rule here is to not break the plane created by the intersecting hallway. Still, you want to see as much as you can before you commit to entering the hallway. Make sure nothing is an immediate danger. Again, crossing the plane created by the intersecting hallway telegraphs your presence to a possible intruder. Now that you have cleared as much as you can without crossing the line, you must break through the plane. Enter to the right. The reason the order of the side is important is because you can turn faster toward your support side than your firing side. If someone ends up being in the corner to your left, you can, more quickly, spin to your left than your right. This is all assuming you are right-handed. Everything should be flipped if you are left handed. Go through diagonally, spotting the corner you are heading toward, and a look over your shoulder to the other corner. View the images to the right for visual representations.

One-sentence summary -- Know what makes T-intersections especially dangerous. Start on the right side of the hallway when approaching a T-intersections. Keep an eye on the right corner as you make your way toward it. Clear the left corner as you would any corner, but do not place any part of your body past where the wall ends. Step back and to the left once you've gotten a view of the left corner. Clear the right corner the same way you did the left corner. Decide to enter. Proceed in a fashion similar to a door.

Staying sane, to a large degree, is about feeling like you are in control of your life. While we cannot control everything, calmly dealing with problems and setting long-term goals will give you a sense of agency and control. Staying sane is about knowing your needs and wants and feeling like you can fulfill them. While it is easy to get caught up in negative emotions, we should remember to talk about what makes us happy. Take the time to write, not just think, a list of things you love in life. Think about what relaxes you, people you love, successes you've had, what you do for fun, and locations where you feel "at home." Resist the urge to be critical. Just think about what makes you happy, whether it is as simple as a cupcake or as complicated as your career. When you feel like you are on the edge, doing something you are good at reinforces your sense of self-worth and purpose. You show yourself that you are capable of creating success and controlling your life. Find a hobby and dedicate time to practice. Taking pride in yourself makes working easier and your accomplishments more fulfilling. " Whether it is being near a co-worker or grocery shopping at the end of the day, you should note the times you feel overwhelmed and avoid the situation next time it comes up. If there is a particular person who makes life difficult, tell them that you are "really sorry, but have to go at the moment," or go to the bathroom for a minute. Excuse yourself from situations where you feel uncontrollable stress or worry, even if it is only briefly. If, for example, you dislike lots of noise, bright lights, and crowded spaces, you may realize that living in a city is not the right lifestyle for staying sane. On the other hand, if you feel content and comfortable when you are with your significant other, remember the importance of that connection when times are tough. Recreate the patterns that promote your sanity, and break the ones that don't. Approach your day from a personal perspective. Think: what do you have to do to be happy? Don't worry about what you have to do to make others happy You are not an illness. Instead of saying "I'm bipolar," say "I have bipolar disorder." Instead of calling yourself "a schizophrenic," say "I have schizophrenia." By not letting a mental health disorder define you, you remain in control of your life and sanity. Having a mental illness is not your "fault."

Not all HP Pavilion laptops have backlit keyboards. If you've been unable to find the option to turn on the backlight thus far, check your computer's manual or online documentation to determine whether or not your keyboard has a backlight. In some cases, your computer's keyboard backlight may not turn on if your computer isn't charged past a certain point while off the charger. You can solve this problem by plugging your computer into its charger. The "Backlight" key is always one of the function keys (typically F5) at the top of your keyboard. It has a symbol resembling three dots on it. If your computer's keyboard is set to use the function keys' hardware features when pressed, this will cycle through your keyboard's brightness settings. You should see the keyboard's backlight dim and brighten accordingly. If nothing happens when you press the "Backlight" key, proceed to the next step. You'll find the Fn key in the lower-left side of the keyboard. If you couldn't turn on the backlight in the last step, holding the Fn key while pressing the "Backlight" button will cause your computer to use the key to change the backlight's brightness. You may have to press the "Backlight" key a few times while holding down Fn to cycle through all of the brightness options.

Try not to let your nerves overcome you before you speak. Whenever you start to feel nervous, start thinking about your talking points instead of thinking about what could go wrong. Then, refocus your mind back on your material. Accept that you will make some mistakes. Embracing the fact that everyone makes small, recoverable mistakes when they speak will help you feel less nervous and keep you from making larger, more critical mistakes. Most minor mistakes won't even be noticed. If you make a minor mistake like mispronouncing a word or skipping a small part, don't stop your presentation or start backtracking. This can interrupt your flow and make you even more nervous. Correct the mistake if you notice it right away. Otherwise, just move on. Close your eyes, inhale deeply by breathing into your abdomen, count slowly to three, and exhale fully. Repeat the process until you feel calmer and you can focus on your points instead of your nerves. This is an especially helpful tool to use right before you have to speak. Actors say and do things onstage that they would never imagine saying or doing in everyday life. That's because actors are playing a character. Think about yourself as a character who is a lot like you, but is really comfortable with public speaking. Play that character when you have to talk in front of your class. This helps some people because when they are playing a character, it is easier to take risks knowing that if you mess up, it's the character that will get the blame, not you. Being an actor is a "fake it until you make it" approach. Play someone who is collected and confident. Given enough time, your confidence will stop being fake. You've worked hard to make sure that this speech goes well, so show it. Your classmates will appreciate watching someone who has a bit of fun with the material. The more enthusiastic you are, the less likely they are to notice minor errors and missteps. Congratulate yourself for having the courage to get up in front of your peers. You will always be harder on yourself than anyone else. Ask yourself what you could do better next time. You can even make a list. Try writing down two positives of your presentation for every negative. This way you can focus on areas where you need to improve without feeling like the whole speech failed.
