Check with Apple Support to verify which type of adapter should be used with your laptop. If you're using a desktop, the power cable is a standard universal computer power cord.

Article: Disappointment is important because it can push you towards productive changes. If something did not work out in your favor, take this disappointment as an opportunity to reevaluate your approach. While a variety of factors can affect your success or failure, it's important to acknowledge which factors you can control. This way, you can reinvent your approach to success. If you're not making sales at work, maybe you need to work on your interpersonal communication skills. Consider enrolling in an online marketing class. If you're struggling to make friends in a new city, maybe it's time to branch out more. Try to get involved in your community. Volunteer for an organization that means something to you. Remember to keep things in perspective. It's important to be self-aware enough to recognize your power in a situation. However, acknowledge what is beyond your control. You can strive to better prepare for your next job interview but this does not necessarily mean you'll be offered the position. See disappointment as a setback rather than a catastrophe. Take a few days to remind yourself of your goals and passions. This can help strengthen your commitment and move past the disappointment. What do you ultimately want from life? Write down your goals or state them out loud to yourself. Remind yourself why these things are important to you. How do they reflect your values and passions? Disappointment can be valuable. If you're feeling particularly let down, this serves as a reminder of how important your goals are to you. If a goal did not mean much to you, you wouldn't feel disappointed. Determination is as important to success as pure talent or intelligence. Take disappointment as an opportunity to push yourself harder. Remind yourself persistence is vital for success in any given field. In the wake of disappointment, develop a strategy to work harder and strive more for success. Take a few days to mourn and then promise yourself you'll start working harder towards your goals.

Article: Let cool water run over your skinned knee, or pour it over it. Do this long enough to make sure that the water has flowed over the entire area, and washed away any loose dirt and/or debris. Use antibacterial soap and water to clean around the wound, but try not to get soap in the wound itself, as this can cause irritation. This will help to wash away bacteria and keep away infection. Hydrogen peroxide and iodine were traditionally used to disinfect skin wounds, such as a skinned knee. However, hydrogen peroxide and iodine can actually damage living cells, so medical professionals now advise that you should not apply them to a wound. If anything is stuck in the wound, like dirt, sand, splinters, etc., use tweezers to carefully remove this material. First clean and sterilize the tweezers by rubbing them with a cotton ball or gauze soaked in isopropyl alcohol. Rinse with cool water once the debris is removed. If dirt or other material is lodged so deep in the wound that you cannot get it out, contact a doctor. Once you have rinsed and washed the skinned knee, gently use a clean cloth or towel to dry the area. Patting rather than rubbing it dry will help you avoid unnecessary pain. This can deter infection and help the wound as it heals. There are numerous types of antibiotic creams and ointments, containing different active ingredients or combinations (bacitracin, neomycin, and polymyxin, for example). Always carefully follow the directions provided with your cream regarding the amount to use and method of application. Some creams have mild analgesics incorporated as pain relief. Some ointments and creams may cause an allergic reaction in some people. If you notice redness, itching, swelling, etc. after using one of these products, stop using it and try another one with a different active ingredient. Make sure to cover your skinned knee with a bandage, to protect it from dirt, infection, and irritation from clothing during the time it needs to heal. You can use an adhesive bandage, or sterile gauze held in place with tape or an elastic band.
