Re-cycling...

Free-lancers are sometimes teased for re-cycyling the same material, over and over and over. It's not a bad idea. You earn more, and you learn more as you go. "Recyclum, Recyclum, Recyclum" .
that's the free lance's marching song
For me it's been demographics, data more generally and the "wedge issues" of politics. You learn as you go. It works,
