Learn to concentrate. It's an important part of listening. Practice such games as "Take 2, plus 3, minus 5, plus 4, times 2, minus 6- what's the answer?" Similar exercises are used in listening-training courses. Cut out distractions. Resolve to put aside the newspaper and stop half-listening to a radio or TV program when someone is trying to talk to you. Repeat instructions. Practice repeating instructions and directions correctly. Unless you can do so, you obviously will not be able to carry them out properly. Good listening isn't easy. Hearing, understanding, and remembering take a great deal of energy. It is hard to listen properly and do anything else at the same time. But good listening pays off. If you recognize and correct any listening faults that may be hurting you, good things may happen. You may listen your way to closer friendships and better relations with your family. You may also get larger paychecks and be more successful in life.
