Brendon Burchard argues that to sustain passion and longevity in a career you must continually challenge yourself and develop new skills. He recommends refreshing your approach (not constantly innovating publicly but growing internally) and gives the example that each of his books was written in a different voice as a deliberate learning practice to become a better writer.
When you have a passion in your life, when you have a career, if there's a long path in front of you that you know is right for you, you must continually shake yourself up. You need to challenge yourself to develop new skills. You need to ask, how could I do this in a new way? So that you stay fresh at it? Not because you need to innovate all the time, but internally, you need that refresh of new skill. Every single book I've written has been in a completely different voice, right? You don't read my books and go, oh, there's Brendan sharing stories. They're more about the framework, more about the teaching. Because I said, I want to be a great writer, and I don't think I am, by the way. I just had to say, I have to learn different styles of writing.
