To develop this ability, you have to train your mind. Most people believe that concentration is a strenuous and tiring activity, and that it involves exertion and tension, which are difficult and unpleasant. This belief, which usually starts at an early age, is not true.
Parents and teachers expect children to study, do their homework and get good grades. Sometimes, they use disciplinary measures against the children. This makes the children feel forced to do something they don't like doing.
Telling a child often, that he or she is not concentrating well enough, creates a subconscious aversion to concentration and study. These become associated with coercion, lack of freedom, and doing something they do not like to do. When children grow up, it is no wonder that their power of concentration is too weak.
Though most people would admit that good concentration is a great asset, yet, most of them, do nothing to strengthen it, because they don't know how, and because they lack the motivation to do so.
Concentration can be fun, if approached in the right way. It should be practiced with joy, positive attitude, optimism, and understanding of its great possibilities.
