As an art teacher I spend more time teaching people HOW to make art than making my own art. This can get pretty discouraging, no matter how much I love working with my students.
However, what I've found, is that I can be equally satisfied watching a sketchbook fill up. Thus, it is my utmost recommendation you keep all your notes, sketches, planning, and demos in a sketchbook. This provides a resource you can easily refer back to and something tangible to remind yourself of all the hard work you're putting it.
