"The man who lets a leader prescribe his course is a wreck being towed to the scrap heap"

This quote by Ayn Rand is an advising to those that permit themselves to be led by someone else. It suggests that if a person permits someone else to determine their decisions and also actions, they are essentially allowing themselves to be taken to a metaphorical scrap heap. This indicates that if a person does not take control of their own life and make their very own choices, they will wind up in a worse scenario than they were previously. It is a pointer to take obligation for one's very own life as well as to not count on someone else to choose for them. It is a suggestion to be independent and also to take control of one's very own destiny. It is a tip to be strong and to not let another person determine one's life.
