A man through his will and determination can achieve anything in this world. Human brain is capable of producing incredible results. God has bestowed human beings with power of logical reasoning and analytical analysis. Man, with the help of science, has come along a long way in doing things, which were once considered as impossible. However, there are certain tasks which are still considered as impossible. For instance, it is believed to be impossible to land on sun. However, the fact remains that no one has tried to go on sun. It is an impossibility only as long as man is undecided about the journey. But, it was also considered to be impossible to land on moon or any other planet of solar system. However, we have landed on moon four decades ago and we are all set to land on Mars. Therefore, the so-called impossible task of travelling to sun would be achieved some day. Similarly, it is consider impossible to cure AIDS (Acquired Immune Deficiency Syndrome), but it was also considered impossible to cure cancer. Therefore, nothing in impossible, if tried. We must apply this principle into our daily lives. We do not embark on many tasks because we consider them to be impossible. The fact that no one else has tried it or some other person has failed to achieve it should not dissuade us from trying it. A work will only be done when we attempt it. Through persistent effort and determination we can achieve many things in this world.
