Have you ever gotten so excited about something that you lose track of what you're supposed to be doing? Let me rephrase that. Have you ever been so passionate about something that - in your effort to develop that passion, streamline it, increase its range of impact - you step back and realize that you've forgotten to continue doing what you're passionate about? It's the difference of working your passion and working on the thing you're passionate about. Can you see the difference? It's subtle. I think the concept is best encapsulated in Voltaire's moral poem La Bégueule - "...the best is the enemy of the good."
