Sir — This refers to the article, “Preaching happiness” (February 9). The Delhi Government’s move to inculcate happiness lessons in the everyday curriculum of Government schools in Delhi is a welcome step that merits much appreciation and attention. As a first step towards enriching academic life with lively engagement with the world around them, this latest step by the Kejriwal Government needs to be introduced in other States too so that young minds can learn to embrace all challenges with a smile, even as positivity, enthusiasm and confidence enthuse them to shine bright and bring out the best within them for the benefit of the society at large.
