I would say it is having these moments of revelation where you have spent ages doing a task inefficiently, only to stumble across a better solution. Well, less stumble, it is more due to the fact that just by being around other driven students who all work in different ways, then strengths can be traded thanks to the great community that is enabled by sharing the course load together.
