Great Grandmaster Dr. Tae Yun Kim, author, speaker, teacher, founder of Jung SuWon Martial Art Academy teaches that we can be our own worst enemy. How?! With just our thoughts! I limit myself and my success every time I tell myself I can’t do something, or I’m afraid, or maybe the person won’t like me, etc, etc, etc. Dr. Tae Yun Kim‘s motto “He can do, She can do, Why not me” is something I can tell myself when my thoughts hold me back from saying or doing what I want to accomplish.
