"Nothing succeeds like success", this statement is very true in its context. Success is what each and every human seek for in their respective field. Success is achieved through a series of failures, without failure you will never know its actual meaning. All desire success but only a few actually taste it with their sweat and constant efforts. You have to struggle for success, experience ups and downs and as quoted by Steve Jobs be determined to "do what you love". You are the producer of your destiny, none shall can snatch it until you give them away.
Some people blame lack of resources being hindrance in their success but if it had been so, what do you think about Walt Disney, Albert Einstein, Steven Spielberg, APJ Abdul Kalam ? There are countless people who regardless of having solid background have reached to great heights. Some other would say they are short of achieving success because of their physical condition and for them Stephen Hawking is the best person to look upon. Ever thought person with disabilities can be first to set forth a cosmology with the application of general theory of relativity and quantum mechanics.
One should be determined in what they desire to achieve in life. Without trying different things you will never know what you are capable of and what miracles you can create. According to me, "One who is not firm, will always be like a worm". People who keep on wandering and never stick to one thing are not acceptable. They are rejected by society because of their unusual behavior towards work and they live in depression leading solitary life without any fun. They seem to be pessimistic in their thought.
But regardless of pointing out deficiencies in other, a successful person thinks in rectifying things. They discover their own ways to handle the situation. In a nutshell, I would like to end this with the popular dialogue of movie 3 Idiots, "Run for excellency, Success will definitely follow you" and then you will feel nothing succeeds like success.
