I’m right there with you; waking up early, writing, getting ready for work, working, and trying to get everything else done around those two requirements.
In order to make it as a writer with a full-time gig, your advice is so sound. It has to become a part of your schedule and never an option. I think so many people start their writing journey, filled with so much hope and energy, but they fizzle out because the 9 to 5 grind can be just that, grinding.
I cheer you on and am curious to hear more about your thoughts because like you, I have no intentions to quit my job, move to a beach and write for my income, but it would be nice….
