Splitting your attention among multiple tasks makes the quality of thought that you're giving to each task less. A recent social and psychological study revealed that chronic multi-tasking in a variety of interactive media makes us poorer students, workers, and less efficient learners. Start prioritizing the most important things you have to do each day and just focus your attention there. Write out a list to start the day, and work through it. Finish one thing before starting another. Even if you find something challenging, stick with it until you're done. Switching between tasks is often more difficult than finishing something you've started. Recent studies show that as short a break as five minutes every hour results in more efficiency than a single long break in the middle of a workday. Let your brain rest and refresh, to give yourself the best chance of staying mentally strong throughout a difficult task. For lots of people, the chatter of the radio in the background, or the noise of the television is part of almost every minute. If you have a lot of white noise and static in your life, try replacing it with soft relaxing music. Let yourself focus on doing one thing only, instead of trying to entertain yourself while you work. Focusing more on what you're doing will have the added benefit of letting you finish your work more quickly. If you're trying to watch a show at the same time, it'll take longer. Want to really eliminate distraction? Get off the Internet. When you're trying to study and Facebook is only a click away, it's awfully tempting to mess around. Use a web-blocker or a site-blocker if you can't unplug yourself. Leave your phone in another room or on silent so you avoid frequently checking it. It may sound overly simple, but one excellent way of focusing your attention back to a task when you find your mind wandering is to remind yourself, "Be here now." Don't think about what you're eating for lunch, or what you're doing later tonight, or what's going to happen this weekend. Just be here now and do what you're doing. Try using a keyword mantra, if you don't like "Be here now." Pick a password or a keyword from what you're doing. If you're doing math homework, make it "math" or another related vocab word. When you notice your attention waning, repeat the keyword until you can re-focus.

One-sentence summary -- Do one thing at a time. Take frequent short breaks. Get rid of distractions. Be here now.

Q: Robusta beans have a bolder taste and up to twice the caffeine of arabica, but most are bitter and less appealing. If you're not a coffee snob and want a more powerful morning kick, you can probably find an acceptable blend with up to 15% robusta. If you prefer a brighter taste, stick to 100% arabica. Opinion is divided among espresso fans, but many do prefer a significant amount of robusta. Despite popular myths, roasting barely affects caffeine content, except for a small decrease after an extremely dark roast. Most people still consider a dark roast "strong" because of its bold, bitter taste. Medium or light roasts won't punch you in the teeth, but they'll keep you just as alert. Keep in mind that it's much easier for a roaster to ruin the flavor with a fully dark roast. Medium-dark roasts (including Vienna and Full-City roasts) also make a strong brew, but tend to have more complex flavor overtones as well. Recently roasted beans have a much more powerful, enjoyable flavor. Try to use all your coffee within one or two weeks to maintain a bold experience. This has no effect on caffeine levels. To keep the beans fresh, store in an airtight container away from light, at room temperature. Try a ceramic container with a metal and rubber latch.
A: Choose a variety. Decide on a roast level. Buy fresh, whole beans.

Article: Each sprayer is different, so read the instruction manual before starting. Usually, you fill the sprayer's bucket with your chosen paint. You then attach the sprayer pump to the bucket. Sprayers usually come with different nozzles depending on which part of the fence you're painting, so choose the correct nozzle to begin. Unless you're only painting a small portion of the fence, choose the largest nozzle first. As you continue painting and need to get into cracks and crevices, use smaller, more precise nozzles as needed. Remember to use an oil-based fence that is safe for wood and exterior use and choose a day that is not very windy. Use horizontal strokes for horizontal panels and vertical strokes for vertical ones. Allow the primer to dry before proceeding. Drying times vary, so refer to the instructions on the can of primer for precise drying times. Keep your nozzle about six to eight inches away from the fence. Use a steady back and forth motion to spray your fence. For horizontal panels, move up and down. For verticals ones, move back and forth. After spraying down one panel, go over your work at a perpendicular line of about 90 degrees. This leaves a crisscross pattern on your fence that eliminates streaks. Make sure not to make arcs at the ends of each stroke. This will spray paint in unwanted places. After your paint dries, examine your fence. Decide whether or not a second coat is necessary. If you chose a quality paint, you can probably get by with a single coat. However, if your paint is a little thin, add an extra coat after the first 1 dries. Check your paint's instructions to see how long it takes to dry. Most paints need to dry overnight.
Question: What is a summary of what this article is about?
Set up your sprayer. Add a layer of primer using a paint brush. Spray your fence. Give your fence an extra coat if necessary.
