Optimism is assuming the best outcome is possible. Pessimism assumes the worst outcome is inevitable. These two different types of people view life entirely differently. However, there is little doubt that optimists are happier, healthier, and generally more successful in all aspects of their lives. A little optimism goes a long way.
Many people believe that one's past determines one's level of optimism or pessimism. To a certain extent, that is true. Children raised to think positively are far more likely to remain optimists than children raised with negativism. However, as adults, we always have choices. Whether we spend our time making lemonade out of lemons or complain about the shortage of lemons is always choice. While optimists see possibilities, pessimists see problems.
