I am always doing self development work and I feel like I can not learn enough fast enough. If there is anything about being an ENTJ that I embody its being a jack of all trades. People ask me if there is anything I don't do. When I am reading and trying to internalize what I am learning it raises a question or a concept I need more information on to have the proper foundation for what I am already working on. My need for information and skill snowballs until I am mentally exhausted.
