The following guidelines for maintaining your focus comes from "How Successful People Think" by John Maxwell. It is a quick, easy read but one of my favorites from Maxwell:
1. Remove distractions: Removing distractions is no small matter in our current culture, but it’s critical. How do you do it? First, by maintaining the discipline of practicing your priorities. Don’t do easy things first or hard things first or urgent things first. Do first things first—the activities that give you the highest return. Second, insulate yourself from distractions. I’ve found that I need blocks of time to think without interruptions. I’ve mastered the art of making myself unavailable when necessary and going off to my “thinking place” so that I can work without interruptions.
2. Make time for focused thinking: Once you have a place to think, you need the time to think. According to researchers, “If you’re trying to accomplish many things at the same time, you’ll get more done by focusing on one task at a time, not by switching constantly from one task to another.”
3. Keep items of focus before you: Ralph Waldo Emerson, the great transcendental thinker, believed, “Concentration is the secret of strength in politics, in war, in trade, in short in all management of human affairs.” To help me concentrate on the things that matter, I work to keep important items before me. I’ll also keep a file or a page on my desk so that I see it every day as I work.
4. Set goals: I believe goals are important. The mind will not focus until it has clear objectives. But the purpose of goals is to focus your attention and give you direction, not to identify a final destination. As you think about your goals, note that they should be:
• Clear enough to be kept in focus.
• Close enough to be achieved.
• Helpful enough to change lives.
David Belasco, who says, “If you can’t write your idea on the back of my business card, you don’t have a clear idea.”
5. Question your progress: Take a good look at yourself from time to time to see whether you are actually making progress. That is the most accurate measure of whether you are making the best use of focused thinking.
