Article: If you're using PowerPoint 2007 or earlier, movie files are not embedded, they're "linked." This means that the video is not actually included in the PowerPoint presentation file. The video file exists separately from the presentation file, and the presentation loads the video file from the specified location. You won't see a literal hyperlink, but PowerPoint will need to have an accurate location of the video on the computer in order to play it. Videos can only be "embedded" (included in the presentation file itself) in PowerPoint 2010 or newer. You can add videos to any slide in your PowerPoint presentation. This will display various options for inserting objects into your presentation. This will open your file browser so that you can select your movie file. PowerPoint 2007 only supports a handful of video formats, including AVI, MPG, and WMV. If you're using AVi files, you may want to convert them to MPG or WMV first to avoid codec issues when trying to play the video. Once you've selected the video, you'll be prompted to select how you want it to start playing. If you select "Automatically," the video will begin playing as soon as the slide opens. If you select "When Clicked," you'll need to click the video to begin playing it. Since your video plays from a specific location, recipients won't be able to watch it if you send them the presentation unless you send the video too. Using the "Package for CD" feature allows you to send the presentation and any associated media as one package. Click the Office button and select "Publish." Select "Package for CD" and then select your presentation. Ensure that "Linked files" is selected in the "Options" menu.
Question: What is a summary of what this article is about?
Place the movie file in the same directory as the PowerPoint file. Open the slide you want to add the video to. Click the "Insert" tab. Click the "Movie" button and select "Movie from File." Browse for the video file you want to link to. Select how you want the video to start playing. Use the "Package for CD" feature if sending the presentation.

Problem: Article: Consider what sets you off and causes you to hunger for what other people have or the way that someone else is. Research has found that often envy results from comparisons to others who are of similar background, ability, and achievements in relative or important areas of one's life. For example, you may compare yourself to a coworker who is of the same status and gender as yourself. The pain of envy is a result of seeing yourself surpassed by another's ability, especially in an area of life that is a deep part of your self-concept by which being surpassed is seen as a threat to your concept of who you are. Some other examples are: You feel insecure when someone else appears more intelligent, funnier, more entertaining, happier or more glamorous than you consider yourself. You cannot help but continuously compare yourself to the other person, either personality-wise or by yearning for the same opportunities they appear to have. You feel deprived and wish for the same property and possessions as someone else. You consider that your life is pale by comparison and somewhat impoverished. You feel miserable because you think that other people have what you don't. Ask yourself what your values are, what your needs are, and what your worldview consists of. Get to the essence of what is really important to you. These things make up your core self-concept. Begin to pull apart the things that are not who you are at your core, and that are causing you to be envious. It is important to understand that people often extend their boundaries of their self-concept to include things that are not necessarily apart of who they are at their core. When these extension areas are threatened, the person often experiences defensiveness, hostility, or envy. Examine if you have extended your boundaries of your self-concept to include other areas such as work, friendships, abilities, or status. Begin to make a distinction between who you are at your core (your values, your needs, your worldview, and your purpose) and what you possess in belongings, personal traits, work success, and identities in your social groups. For example, say you give a presentation at work, and you interpret criticisms of the presentation as a personal attack. This means that you have extended your self-concept to include your work. In fact, however, you are not your work, and it is not a part of who you are at your core. Your work is simply something you do. Yes, it is part of your life experience, but it is not who you are as a person, and it is not your personality trait. In another example, you may be envious of a friend in your social group who is similar to yourself. Perhaps you are usually the entertainer in the group or the one making others laugh. When this friend's talent for making others laugh surpasses your own, you may see this as a threat to your self-concept. In actuality, you are not your ability to entertain others. Who you are at your core is much more than this one trait. These types of scenarios are more common for those who suffer from low self-esteem. This is because their evaluations of themselves are lower than how they evaluate those around them, thus producing feelings of envy. Envy is a complicated emotion that has many facets and can take many forms. Research has found that envy can be social in nature when one perceives that he or she is being left out of the group or left behind because they are being outperformed by another in the group. Studies have found that some types of envy, termed "envy proper", contain feelings of hostility, whereas others forms of envy, termed "benign envy", do not include feelings of hostility. In addition, researchers make a distinction between envy and jealousy, noting the envy is a feeling of inferiority when compared to another, whereas jealousy involves three persons and stems from being afraid of losing a relationship with one person to another.
Summary: Identify what sparks your envy. Write down your values, needs and worldview. Recognize if you're extending the boundaries of your core self-concept. Recognize some of the characteristics of envy.

Both before and after you attempt to fix a gas leak, you need to make sure that the area is well-ventilated. If the area is not well-ventilated, you may have a potentially dangerous accumulation of gas. Open windows and doors. Allow an area to air out before re-entering it or turning on any appliances. If you have any doubt that you've fixed the gas leak, you should not engage in any activity that could result in a gas explosion. This is important, as any fire or electronic activity could potentially ignite accumulated gas. Refrain from: Lighting matches or lighters. Operating electrical switches. Using telephones. Answering your cell phone or using other portable electronic devices. The second you suspect there is an ongoing gas leak, you should vacate the building at once. This is important, as gas leaks can quickly turn into gas explosions. In addition, you might also be overcome by the gas and lose consciousness. After exiting the building, stay at least 100 feet away. If safe, and if you know where it is, locate the gas shut off valve and turn off the gas for the premises. After exiting the building, you should call a professional to properly fix the gas leak.
