Expecting the worst case scenario has always seemed more logical. The best case scenario is implied, while the worst can often be overlooked which can lead to hard-to-deal-with situations.
Concerning the goal, from what I understand it concerns one/few big goals, where one has to work hard for a long time before reaching it/them. Would smaller goals be a better approach? I tend to set many small goals, such as finishing this task by the end of the week, and I instinctively expend them as I complete them. If I realize their impact is smaller than expected, or that they even don't matter much, I tend to just forget them and move on with more important tasks. It keeps them flexible and actually forcing me to do things I'm not even sure I would if it wasn't for these small goals. By keeping goals flexible and smaller, I believe they can actually help to achieve something bigger.
