Find some time for recreation, studies, social service or mingle more with the people nearby thus breaking the patterns of habitual negative thinking. It is said that better late than never. You are on the go. Congratulations ! Further, as we cannot stop functioning of the organs like heart, liver, kidney and digestive systems, we cannot make our brain stop doing its duty of thinking, as the brain does not have the cognitive awareness of good or bad. It is our duty to break the chain of thinking and channelize the power of thinking for a rational subject or matter. The brain is like a grinding machine which grinds whatever you put in. So try to put something of use to the machine. Albeit, it may take sometime to change the thinking pattern, your conscious effort will yield amazing results within a short span of time. If you follow this, you will find yourself smiling at it in a later stage. Change yourself ! Prayers, Dr Rajesh, Rehabilitation Psychologist, India
