“Achieving strategic clarity is hard. It takes asking tough questions about tradeoffs, deep concentration to get to the very essence of the issues and real courage to cut off competing priorities. It is worth the effort because with real clarity, people, teams and organizations can fully mobilize, break through to the next level and achieve something truly great.”

As quoted in "In conversation with Kate Bush" by Elio Iannacci in MacLeans (28 November 2016)
Context: The great thing about art on any level is that it can speak to all people if it’s achieved properly. When I’ve heard a piece of music or seen a painting that moves me, it gives me something. That’s such an incredibly special experience. I have intentions as a writer, but people — when they’re listening to a track — will take from it what they interpret. Sometimes people mishear my lyrics and think a song’s about something it isn’t. That doesn’t matter. If it speaks to them and they get something positive from it, it’s great.
