I always get to about 30 shots on a roll of film then just want to finish it as quickly as possible so I can have it processed. It's almost as if those last 6 shots don't really matter as its all about getting that film out of the camera.
I was in the same predicament the other day so I chose some random objects (including the discards of my dinner preparation!) and snapped away. It took all of 10 minutes. For someone that over-thinks everything - especially when it comes to a creative outcome it was really liberating to shoot away with the freedom of not worrying about the consequences. Definitely some food for thought moving forward!
