The single most important skill for successful completion of higher education is reading with comprehension. Since most of your college work will involve reading, the development of your reading skills should be a priority.
All readers experience the exasperation associated with attention drift.
Your interest in the subject greatly influences the span of your concentration. While they may read a complete article in a popular magazine with hardly a blink of an eye, most students, however, have difficulty concentrating very long on a page in a textbook. Then, get up and run the errand, make the phone call, or fix the snack. Whatever the diversion, when you come back to the reading, do so with a commitment to reading with concentration at least the same amount of text you did before before you will allow yourself to drift again. This kind of conscious efforting will result in a gradual lengthening of your concentration and discipline as a reader.
