Research is a long process, so the main driving factor is motivation. For some researchers and post-graduate students, the main objective behind the research is to earn a degree. For organizations including defence and research laboratories, research is an important aspect. To philosophers and thinkers, research may mean the outlet for new ideas and insights, whereas to intellectual people research may mean the development of new styles and creative work. Irrespective of any domain, research demands passion.
Initially, the research is a random walk (research scholar is not sure about topic/research problem), but one needs to systematically continue to get the destination. Failure is an inevitable step in the research phase, for example, failure in getting results, publications, and so on. But the researcher’s passion and motivation helps in such situations.
