Definitely brings the question: "Am I doing my life's work?" to the foreground of my mind. I believe I am, the integrity of my work is not compromised - I have the autonomy & leisure of thinking through every single detail that comes to mind. I'm only concerned with doing it right, not rushing or worrying about any competition.
It's a great feeling to feel like you're doing your life's work, especially when your vision for it is so much bigger than what you've already completed & feel proud of.
