"He has sat on the fence so long that the iron has entered his soul"

This quote by David Lloyd George is a metaphor for someone who has been indecisive for so long that it has become a part of their character. It suggests that the individual has been so hesitant to decide that they have actually ended up being solidified and unyielding in their views. The expression "iron has actually entered his soul" suggests that the person has actually become so established in their indecision that it has become a part of their identity. This quote is a warning to those who are hesitant to make choices, as it recommends that the longer one waits, the more difficult it will be to make a choice. It is a suggestion that it is very important to make decisions in a timely manner, as the longer one waits, the harder it will be to make a modification.
