Do you see the glass as half-full rather than hall empty? The two different answers to the question represent two different attitudes towards life -- optimistic attitude and pessimistic attitude.
　　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 challenges and disappointments in very different ways. When things go wong the pessimist tends to blame himsell, while the optimist looks for loop holes. The optimist feels in control of his oval life. If things are going badly, he acts quickly, looking for solutions, forming a new plan of action, and seeking for advice. On the contrary, the pessimist yields to the arrangement of fate and moves slowly. He doesn't seek advice, since he assumes nothing can be done.
　　Most people are a mix of optimism and pessimism. Optimism is important in all aspects of our lives. If you can change your mind from pessimism to optimism, you can change your life.
