I chose the quote “Believe you can and you’re halfway there.” Theodore Roosevelt I think it means that having faith in yourself is half the battle. If you don't believe in yourself, how do you expect others to believe in you? Well, when I grow up I want to be a veterinarian, I believe I can do it and other people should support me. :D I think it can some people put themselves down and say things are impossible, nothing is impossible so if they believe, they can achieve pretty much anything. More people would probably have better spirits that is one way it would impact the world. That how I express what the poem means.
