I would suggest two approaches to begin the leadership journey in earnest. First would be to ask oneself, in every interaction with others over the course of a single day: How can you best serve this person? Another approach would be to attempt, over the course of a single day, to reframe your declarative statements into questions. The thoughtful use of questions can be transformational. In my experience, most people find these exercises more challenging - and more rewarding - than they would have imagined.
