请根据以下提示, 结合生活中的一个事例, 就“乐观”这一话题, 用英语写一篇短文。
Optimism always leads to happiness, health and success while pessimism, by contrast, results in hopelessness, sickness and failure. That’s because optimists and pessimists deal with the same challenge and disappointment in very different ways.
注意: 1.不得照抄英语提示语;    2.内容必须结合生活中的一个事例;
3. 词数为100-120左右。
