A good reader reads fast and understands most of what he or she reads. Although each person is different, most good readers share six characteristics.
    First, most good readers read a great deal. They make time for reading and spend two full hours a day, three or four days a week, reading.
    Second, Past readers look for the main ideas in their reading. They don’t waste time and effort on unimportant details.
    Third, good readers improve their comprehension ability by reading more and more difficult materials.
    Fourth, fast readers plan their time for reading. Like students with assignments, good readers give themselves time limits, saying "I want to finish this book by tomorrow. How much time can 1 spend?"
    Fifth, good readers set goals. To set a goal, they may read for fifteen minutes for quick understanding, then count the number of pages read and multiply by four. This gives them a number of pages to try to read each hour. Gradually, they increase these goals.
    Lastly, fast readers concentrate. They do not let outside distractions or daydreams interfere with their reading.
