Step-by-step approach key to big research!

As a graduate student, I notice how important it is to have a balanced research goal. It used to be the case when I approach a research problem, I try to solve it in its entirety, & then get bogged down with its enormity & waste a lot of time. Now I have learnt that it is important to dissect one big problem into smaller ones, and do step by step. The target should always be decent and acheivable. Gradually, these small successes will contribute it to make a big one & complete the mosaic. Also, it is more convenient to publish results in conference step-wise whenever you have a result. It also helps to get the feedback and improve on anything. Finally, the gradual step entitles you more understanding of the big problem, and according you will target it.
