I love the idea of mixing it up. Sometimes I just do not feel like being in front of the camera and mixing it up stratgy allows me to do that without feeling guilty. The days i feel I look good I go in front of the camera and other days I just to audio!

One thing I would add is take a break, especially when filming yourself. The frustration of making mistakes can get to you but if you walk away from it, you come back with a fresh mind. Works a treat for me.
