“To believe your own thought to believe that what is true for you in your private heart. Is true for all men: every heart vibrates to that iron string.” I think that the poet is trying to say that if one believes in them strongly enough anything is possible. Also, that if one puts all there effort into making something happen, anything is possible. For example, the creator of We Day, Craig Kielberger. He had a dream to make the world better for people in need. He put is mind ot something and he succeeded and now has a very successful charity. Furthermore, when I needed to do well on a math test last year, I set my mind to it and studied very hard, and ended up getting a really good grade. In conclusion, I believe when making decisions in our day to day lives, this quote is demonstrated, because everyone believes in something and has dreams that if they try their best the can become a reality.
