The author says "how dull it is to pause, to make an end, to rust unfurnished, not to shine in use."

These lines specifically apply to things that I want to do before I die. There are places that I want to go, things that I wish to see, and people that I want to meet. There are many things that I will do before I die and my margin will never fade away because I will always find something new that I wish to do. I will do what has not been done, I will see what has not been seen, and I will meet with people that I thought I would never meet. .
