A grain of sand does not represent much in isolation. Placed with many others, it becomes a beach. This metaphor exemplifies what happens with our contributions to the world of research. The research carried out by many of us occurs in specific contexts, takes small samples and its generalizations are applicable to reduced populations. We expect that our results may contribute to the solution of a local situation or problem. Placed together in the long run, the small and the big contributions may cause a great impact in the field of study or work in which we develop our professional life.
