I like to draw and paint. When I practise, I find reference photos to mimic still-life drawing. Every time I tell myself that I should practise (becoming a better type designer and letterer), I always get stuck as to how I should practise that. If you teach type design, what kind of exercises do you give to your students? As for the more technical aspects, I find tutorials on Glyphsapp.com and try to repeat the techniques inside the application.
