Power in positive thinking

Is there power in positive thinking? In my own opinion I believe that there is power in positive thinking. Positive thinking is a mental attitude that admits into the mind thoughts, words and images that are conductive to growth, expansion and success. The mental attitude of thinking positive expects good results and being positive about things it can lead you to be happy. Mostly everyone had things they wanted really badly and once that emotion hits in, all we can do is formulating the desire in our head. Having thoughts of obtaining it one day we just might grasp it. If one does not think positive in everything they do or they tend to doubt themselves then they wouldn’t believe that there is power towards positive thinking, but having such negative thinking it’s never too late to change one’s mind.
Have you ever wonder about how some people become so famous? It’s because they had this ideal goal in their mind to pursue this passion of theirs and all they can do is think about it none stop until they got what they want. Taylor swift who is a 19 year old, country girl music singer, at the age of nine she had realized she loved to write songs and sing. All she ever thought about was how she can make it big and be famous one day. She had never doubt herself and deciding to give up; she had this positive emotion telling her that she can do it. As she kept on trying and being positive her dream finally came true, she had won many music awards and is now well known.
Being negative will just lead to depression and unsatisfying results. One of my friend who has very low self-esteem, he had considered himself as a failure and a loser he was sure that he would never get a girlfriend. With a negative attitude towards himself, he had not tried talking to any girls and rejected himself of being unworthy. Doing so he have not been in a relationship for 2 years and if he never change his negative thinking into positive then the wait might just be longer.
