One thing that I have noticed over the years is that there is a BIG difference between what people think they need in order to be successful and what they actually need to be successful. For instance, let’s say that you are going to repel off the edge of a cliff. Hey, it could happen; I know someone that jumps out of perfectly good airplanes, but that’s another subject. So by your estimation, you figure it is about 1000 feet down. Beside you is a 1000 and a 2000 foot rope. Which rope do you use?
a) 1000 foot rope
b) 2000 foot rope
If you chose the b) 2000 foot rope then you have chosen wisely. If you chose the 1000 foot rope what would happen if you were 50 feet short? That is one long! The point of the story is that sometimes it is better to do more than what you think you need so there is room for error.
