The people who accomplish the most are never satisfied with how much they have accomplished. Series of accomplishments require continuous accomplishing, which requires motivation. These high-achievers continue to accomplish so much because they constantly motivate themselves with thoughts of inadequacy. I assume most people only follow others who they see as more accomplished than themselves in some way. By definition you must follow someone in order to compare yourself to them. Thus, you must only compare yourself to people more accomplished than you. By doing do, you promote in yourself the same feelings of inadequacy that drive thr most acccomplished people.
tl;dr Compare your accomplishments to greater accomplishments by other people. Feelings of inadequacy will motivate you to accomplish more.
