Hey Max,
First of all, let me also echo what so many other have said in that this was a great post... and very timely. I love the first point on music. As a musician (please, don't hold that against me), my band is always looking to write something new and "catchy". Not an easy task in a world of Lady GaGa and Justin Bieber. While we try to create something new, we also try to focus on something that will draw people into the song.
I find this can be very similar in leadership. As an emerging leader, I find that I'm faced with the daunting task of creating something new but recognizable. In other words, the overall "tone" must be one that people are drawn to. I appreciate what Kelly shared about tradition. Many of the leaders I work with are very proud of their traditions. I often find that they are usually more open to new suggestions when I take their background, challenges, successes, and culture into consideration. Instead of trying to revamp the song, I try instead to enhance the sound quality. I never really appeciate when someone tries to remake a classic like Rudolf. It's just not the same and there's no thought or creativity put into it.
Best, Jake
