One thing I learned when doing a photography MA a few years back was just how useful a reflective journal can be. I tried to keep it going when the course ended but it was not easy. For some reason, I started a new journal on 1 April this year using a hard-back notebook which seemed a bit more substantial than the usual cheap pads I used previously.
I have made regular entries about processes I am trying or revisiting and it helps to get a better perspective on what works or fails. This morning just writing about something that was just not right helped to find a better option. And being critical about what I did a few weeks back has raised questions about the process. I recommend giving it a try.
