I like your thoughtful and deliberate approach to your professional, volunteer, and writing goals. This makes a lot of sense to me, but the waking up at 5 am still sounds challenging. I guess there's always some pain with progress?
Best wishes to you as you carve out more space for writing! I hope you're able to make that transition to full-time writing someday soon. It strikes me as a worthy goal but there's definitely going to be lot of hustle to make it happen. So having a deliberate approach as you've outlined here sets you up for success!
