This quote is basically saying that you have to expand your mind to be capable of accomplishing things. If you think less of yourself, you will become less. If you think more of yourself, you will become more and accomplish more. We can learn that we need to broaden our minds and set our goals higher so we aim higher for success. We can apply this to our lives even in school. For example, let’s say someone has a big test, if they tell themselves they will never be able to do it, then they obviously won’t. Although if they think they can do it, and they study hard and have that mindset of thinking they can do it, then they will pass. We need to start thinking that we can do more.
