I was a boy scout in Troop 456. Once during a Scout-a-rama relay, my tenderfeet carried me up a 20' repelling tower. I was the most novice in the troup. When I reached the top, I took one look down at the earth below and froze with fear. We lost the relay. An early lesson that indecisiveness is failure. Patience and sober judgement- good. Indecisiveness (especially when the clock is ticking)- bad.
Frozen? Then decide, and the thaw will begin.
