I've really taken this to heart and found that there are entire categories of "high-involvement" tasks that I'm simply not up to outside of my peak energy periods (mornings) but that still need to get done. Even breaking those high-involvement tasks down to micro tasks I find that my low-energy intervals can deal with some of those quite well.
I sew when I'm brain dead and hate working. Not even organizing/grunt work sounds appealing, so I'll design and make some sweaters.
Ive also found getting stuck in a favorite video game has helped productivity. When I'd rather work than get past a hard spot, I'll keep working. Similar is true if you simply uninstall a large game.
