The more I write out my thoughts, the more I understand myself and the more I want to write out my thoughts.
I too journal my thoughts on the day in my Bullet Journal. Sometimes it's intimate, sometimes it's me saying I wish I could read more without needing to do "billable" hours for clients.
Joe also talks about the burnout of sticking with productivity and how-to articles. I was "freelance" only for a long time. While I still write to help you run a better business, I also write about other things like spending time in the mountains and really whatever sparks my fancy.
I will continue to write about whatever interests me.
