Once upon a time, there existed 5 people; these five people's names were 'A', 'B', 'C', 'D', and 'E'. Day 1: On day one, the leader, whose name was 'Z', gave orders to 'A', 'B', 'C', 'D', and 'E' and upon giving orders, asked who would like to volunteer. The first to volunteer (for ease of explanation) was person A. Every time, person A volunteered, no matter what the task. The interesting thing was that on Day 1, 'A', 'B', 'C', 'D', and 'E' had equal knowledge and experience, but since A was the first to volunteer, A gained the first experience. Each person volunteered according to their letter ranking: A ahead of B, B ahead of C, C ahead of D, and D ahead of E. The rank was an indicator of their confidence. A was more confident than B, B more confident than C, etc. By day 20 or so, A was far ahead of E in experience and knowledge, and E had no idea why.
This parable actually reflects a lesson I learned in Air Force ROTC. In training, when the leader makes a command for a task to be done, all soldiers/cadets/personnel will eventually have to follow the command. The last person to volunteer winds up being the least experienced. Have the confidence to volunteer early!
