Many leaders strive do this through reading, listening to podcast or seminars about leadership. All of those are valuable ways to shape our personal growth. I always try to encourage people who ask me about blogging, to try it for a week. Then see the thoughts that spark within you and how it develops your team.
I relay this concept to professional athletes, and how they work so hard to be in peak physical condition in the off season and in practice during the season. They lift weights, run and train specifically for their sport. So when the reach game time they are ready to go. If this is true of athletes, it should be true of leaders. We shouldn't expect greatness to just appear, we must work to improve ourselves daily. So that once we our with our team/organization the ideas that we study come to pass.
In closing, it is important to continue to have gains in your personal growth so that it will contribute your personal success. As you champion this concepts, leadership become less work and more influence to those around you in your team/organization. Because the thoughts you write down, now are not only thoughts, but shape who you are in leadership.
