In his article, "In the pursuit of happiness", Professor Abdul Shakoor Shah writes:
"Focus on more happy and optimistic thoughts. Prioritize the positive aspects in different problems and issues in life because there are two parts to developing helpful and optimistic thinking.
"The first is to eliminate unhelpful negative thoughts and the second is to plant more positive and optimistic thoughts.
"The pursuit of happiness is fundamentally a skill, and like any other skill becomes easier and more effective with practice."
