If the choices are equal and the consequences unimportant, make the choice quickly and move on. Students often get stuck deciding which topic to choose for written assignments or for optional sections on exams. Often it is best to decide quickly and simply get going before time runs out. If, however, it is important that you choose the best course of action, then random is not appropriate. Again, most of us can learn something from Lance.
Lance is a brilliant software engineer.
Much of his efficiencycomes from his approach to problems. Once he is satisfied that these questions have been answered, he will simply go ahead and implement the choice. He will not spend any time or energy second guessing the choice to move ahead because he did the analysis up front. Now this approach may seem contrary to the random approach, but it is a process of identifying what is the most important and giving attention to that, rather than spending time and energy on insignificant items. I truly believe that we can all can be successful at the challenges of school and life in general if we learn to focus on what is important and reduce the time and energy spent on unimportant or counterproductive activities.
