I can relate. I am mostly just trying to put out new content, but I often go back and try to update older material as well. I enjoy either just fine, but I have so much going on that it is way too easy to find a month gone by without any meaningful content.
I keep thinking that if I could make it a full time gig that would be the solution, but I can see how I would find myself in a similar situation as you are describing.
It's hard to be accountable to ourselves. Maybe we need someone to crack the whip at us!
