We don’t need to stay physically active to remain engaged and effective. To achieve our 
goal, sometimes it is better to take a step back and reflect than behaving like a chicken with no head.
For example, during my first aid training last month, as a scenario practice, the instructor split 10 of us into 2 groups, first aider and causality groups. I was one of the 5 people in the first aider group. The scenario was that the 5 causalities somehow stacked up against each other. After the practice, the instructor said that the first aider group made a common mistake of NOT calling the ambulance while everyone was frantically trying to help. In addition, there was no planning on how the causalities should be rescued. The instructor said it would be wiser if we assessed the situation first and planned accordingly.
A lesson learned and it is well summarized as “Buy time – but don’t postpone forever. Think, research, mull, then go for it.” in the book Sort Your Brain Out by Dr. Jack Lewis & Adrian Webster.
