We should thinking positively

We should thinking positively
Our states of mind have great influence over our life, and the quality of life depends much on our attitudes towards life.
In my opinion, thinking positively is a good way to have a happy life. As an instance, some old men who choose to highlight the positive have lived longer than other pessimists. The optimists hold the view that having optimistic attitudes towards life is more important than the pessimistic attitudes. Provided that we keep smiling every day, every good thing will  be happened.
In general, when we meet quite a few failures, we feel frustrated and look down in despair. Can we shift our perspective that we often view the bad things? I have a thought that success can't leave optimism, and the key to success is to be an optimist. A winner often put the optimistic attitude in the first place. They don't keep the melancholy mood for a long time. Additionally, they will try another way to transform the bad situation. This is why the loser often fails and the winner often succeeds.
How can we keep an optimistic and positive attitude? On the one hand, do more sports and read more books which can let us happy in our daily life. While we are under stress, we should try our favorite way to relax ourselves. On the other hand, learn to shift our perspective. When we meet some difficulties, we need to look on the bright side and look up in hope. Just in this way, can we keep an optimistic and positive attitude to cope with trouble.
It's important for us to think positively. If everyone were an optimist, our world will be better.
