Help please 
 Read the following paragraph:
 "Humans have a natural tendency to focus on the negative: studies show our brains react to and remember unpleasant experiences
 about five times more strongly than pleasant ones. This may have helped our ancestors survive in the wild when they were constantly
 surrounded by dangers, but these days it can lead to depression rather than safety. Psychologists say that we can overcome this instinct by
 deliberately choosing to celebrate small occasions and successes. The practice, they say, has a number of benefits. In the short term,
 smiling and laughing release chemicals that improve mood and feelings of well-being. Over time, learning to focus on the positive
 develops skills for maintaining self-esteem and increases overall happiness. It can even lead to the formation of new pathways in the brain
 that make easier to cope with negative emotions."
