Its one thing to think, and its another thing to think wisely,which are you doing ? The fact remains; you are what you think and make people think about you. So many people have developed a persistent permanent habit of negativity about themselves and about issues concerning them and this limits them greatly. That it did not work today does not mean it will never work why not think of some other ways of doing that thing. If someone could try an experiment for 999 times, who are you to try thirty times and say it can never work. You can do whatever you believe you can do so get up from your dung hill of mess, disappointment,failure, weakness, hopelessness and what have you today. Test the other side of life today and you will see that its worth a test. Its a choice.
Be a positive thinker!
