Many people run after goals that they hope will make them happy, but happiness is not always the final result. So how does one decide which goals will end in personal happiness and which will not？How do the things in life affect personal happiness?

The most important thing is people’s attitude toward life, which can greatly affect their personal levels of happiness and satisfaction with life.

Psychologists have known for some time that optimism is a good way to fight against unhappiness. It’s probably no secret that optimistic people are considered to be much happier people than pessimists. There are specific characteristic features optimists have (pleasant ways of thinking), that bring them more success, greater health, increased life satisfaction, and other good things. If you became an optimist, it can mean that you became a very happy person, despite your circumstances, and it can actually bring more things into your life to be happy about. “If you are optimistic and you think life is going to get better, it will become a self­fulfillment prediction.” says one of the scientists. “Happy people manage to look on the bright side, even if they meet big problems on their way.”

Positive psychologists believe that people can learn how to become happy and that everyone can teach themselves to see a half empty glass as half full. All they have to do is to spend time thinking about all the things that have gone right for them, rather than complaining what has gone badly. But people who are depressed usually think and worry about something that went wrong in the past.
